Thank Jehovah for the Ranson Sacrifice of Jesus Christ.

11 While they were listening to these things, he told another illustration, because he was near Jerusalem and they thought that the Kingdom of God was going to appear instantly.+ 12 So he said: “A man of noble birth traveled to a distant land+ to secure kingly power for himself and to return. 13 Calling ten of his slaves, he gave them ten miʹnas* and told them, ‘Do business with these until I come.’+ 14 But his citizens hated him and sent out a body of ambassadors after him to say, ‘We do not want this man to become king over us.’
15 “When he eventually got back after having secured the kingly power,* he summoned the slaves to whom he had given the money,* in order to ascertain what they had gained by their business activity.+ 16 So the first one came forward and said, ‘Lord, your miʹna gained ten miʹnas.’+17 He said to him, ‘Well done, good slave! Because in a very small matter you have proved yourself faithful, hold authority over ten cities.’+ 18 Now the second came, saying, ‘Your miʹna, Lord, made five miʹnas.’+ 19 He said to this one as well, ‘You too be in charge of five cities.’ 20 But another one came, saying, ‘Lord, here is your miʹna that I kept hidden away in a cloth. 21 You see, I was in fear of you, because you are a harsh man; you take what you did not deposit, and you reap what you did not sow.’+ 22 He said to him, ‘By your own words I judge you, wicked slave. You knew, did you, that I am a harsh man, taking what I did not deposit and reaping what I did not sow?+ 23 So why did you not put my money* in a bank? Then on my coming, I would have collected it with interest.’
24 “With that he said to those standing by, ‘Take the miʹna from him and give it to the one who has the ten miʹnas.’+ 25 But they said to him, ‘Lord, he has ten miʹnas!’— 26 ‘I say to you, to everyone who has, more will be given, but from the one who does not have, even what he has will be taken away.+ 27 Moreover, bring these enemies of mine here who did not want me to become king over them and execute them in front of me.’” - Luke 19
 
"to secure" implies a process. A period of time. 
 
36 As he moved along, they were spreading their outer garments on the road.+ 37 As soon as he got near the road down the Mount of Olives, the whole multitude of the disciples began to rejoice and to praise God with a loud voice because of all the powerful works they had seen, 38 saying: “Blessed is the one coming as the King in Jehovah’s* name! Peace in heaven, and glory in the heights above!”+ 39 However, some of the Pharisees from the crowd said to him: “Teacher, rebuke your disciples.”+40 But in reply he said: “I tell you, if these remained silent, the stones would cry out.” - Luke 19
 
"AS the King" is the phrase used... not "as king"
 
------------------------------------------------------------------
 
An often used phrase we heard 30 years ago was "King-designate" 
--------------------------------------------------------------------------
This inspired psalm gave the Hebrews reason to regard the promised Messiah as the one in whom the office of priest and king would be combined. The apostle Paul, in the letter to the Hebrews, removed any doubt about the identity of the one foretold, speaking of “Jesus, who has become a high priest according to the manner of Melchizedek forever.”
 
Ps 110
Jehovah declared to my Lord:   
“Sit at my right hand+                    (10 days after Jesus' ascension on Pentecost 33 C.E)
Until I place your enemies as a stool for your feet.”+ 
 2 Jehovah will extend the scepter of your power out of Zion, saying:               (1914)
“Go subduing in the midst of your enemies.”+
 3 Your people will offer themselves willingly on the day of your military force.*    (1914 ...)
In splendid holiness, from the womb of the dawn,                               (Birth of a nation....)
You have your company of young men just like dewdrops.         
 4 Jehovah has sworn an oath, and he will not change his mind:*                   (29 B.C.E.)
“You are a priest forever+                                             
In the manner of Mel·chizʹe·dek!”+
 5 Jehovah will be at your right hand;+
He will crush kings on the day of his anger.+                                          (ARMAGEDDON)
 6 He will execute judgment against* the nations;+    
He will fill the land with dead bodies.+        
He will crush the leader* of a vast land.*                                           (SATAN in the abyss)
 7 He* will drink from the stream along the road.                                           (New World)
Therefore, he will hold his head high.                                            
 
So to @JW Insider Your proposed scenario would make verses 1,2,3, 4 all happen simultaneously?  

The spirit itself bears witness with our spirit that we are God’s children.—Rom. 8:16.
If you are an anointed Christian, the heavenly hope is an important subject of your personal prayers. When the Bible speaks of being ‘promised in marriage’ to the heavenly Bridegroom, Jesus Christ, you apply that to yourself, and you look forward to being part of Christ’s “bride.” (2 Cor. 11:2; John 3:27-29; Rev. 21:2, 9-14) When God in his Word expresses his love for his spiritual children, you respond, “That means me.” And when Jehovah’s Word gives instructions to his anointed sons, holy spirit moves you to obey and to say in your heart, “That applies to me.” God’s spirit and your spirit thus join in bearing witness that you have the heavenly hope. On the other hand, if you are part of the “great crowd” of “other sheep,” God has given you the earthly hope. (Rev. 7:9; John 10:16) You want to live forever in Paradise, and you find joy in meditating on what the Bible says about future life on earth. w15 1/15 2:16-18

Just thought I'd weigh in. I read through the entire exchange on Saturnalia with Ann as it was happening, before and after various edits and deletions and commentary about those edits and deletions. I believe that Ann is being very accurate in the way she described it when she says:
You rehashed Hislopian misconceptions, tried to pass off fiction and fable as historical fact, and copy-pasted any old bits of nonsense off the internet in a vain attempt to add weight to sensationalist, unverified claims about ancient Christmas practice.
In fact, she might be being just a bit too generous and kind with that characterization.
Other than that, I agree that the date is not as important as the Memorial itself. The scriptures speak about passing and partaking of the bread and wine, but they are quite vague even about how often. The evidence shows that many early Christians preferred yearly, and this makes the most sense. Even the original Passover could be celebrated a month late according to the Mosaic Law.

I would agree, but the Org likes to pride itself on getting the date and time 'just right.' If it's not important to have The Most Important Day of the Year on the right day, then why not use western Christianity's dating system?
'Erred view'? Lol, I think your memory might be tricking you.

Ann,
That's a very powerful combination of points. I remember when Brother Schroeder at Bethel was getting himself involved in the "generation" debate. He needed to look at all uses of "generation" in contexts that implied a time-frame. He was willing to go to Josephus, Philo, the Pseudepigrapha. He was not really satisfied with any of the solutions that went beyond 40 years. He was willing to go with either the solution that it meant the "wicked" generation or the "anointed" generation but, either way,he still wanted it to be within 40 years. 
So it shouldn't have been surprising that he came up with the idea that, because of Sputnik, October 4, 1957 was the new, updated start of the generation that saw the full sign, because it had to include the "signs in the 'heavens'" including the idea that men would become 'faint out of fear.' It's also interesting that even though we have never claimed that Jerusalem fell in October, or that Zedekiah was removed from his throne in October, we still love the idea of October as the start of the Gentile Times. Not just October, but October 4th. 
*** w79 9/15 p. 24 par. 11 The “Cup” That All Nations Must Drink at God’s Hand *** [1979]
But the reason simply is that about October 4/5, 1914, or 2,520 years from the desolating of Judah and Jerusalem after the Babylonian conquest, the Gentile Times of uninterrupted world domination ended.
Note the wording of the very first line on http://history.nasa.gov/sputnik/
"History changed on October 4, 1957, when the Soviet Union successfully launched Sputnik I.".
1957 + 40 = 1997, and he was also sure that the end would come before the end of the 20th century. The proposal was in 1980, and therefore he was sure that we had less than 17 years left in this old system.
*** w80 7/1 p. 3 Keep Watching! *** [1980]
Truly, the possibility that the “unthinkable” could happen provides good reason for thinking about the world situation. And many people are thinking. A special report in the February 11, 1980, issue of U.S. News & World Report analyzed the military might of the leading nations on earth, with these opening words: “To a fearfully watching world, the Soviet Union today looks like a military juggernaut, driving relentlessly toward global domination.” This is indeed a fearfully watching world, for the kind of holocaust that would accompany a nuclear war simply beggars the imagination. And there is no question that global domination has in fact become a major issue of our times.
Is there any solution to this doomsday situation? Many persons watch in despair. They see the nations ‘beefing it up’ in terms of rockets, submarine-launched ballistic missiles, long-range bombers, nuclear warheads and the like. As they watch, they become painfully aware that fearful dangers now threaten from the heavens and the sea, even as the Master, Jesus, foretold for the final days of the wicked system of things on this earth. Jesus said:

“There will be fearful sights and from heaven great signs. Also, there will be signs in sun and moon and stars, and on the earth anguish of nations, not knowing the way out because of the roaring of the sea and its agitation, while men become faint out of fear and expectation of the things coming upon the inhabited earth; for the powers of the heavens will be shaken.”—Luke 21:11, 25, 26.
In this context, it's easier to understand why Brother Schroeder was able to propose the following, with the approval of two other members of the Governing Body and propose it to the entire Governing Body.on March 5 of the same year, 1980:

The exact pronunciation is not known anymore. So, as to the validity of "Jehovah".
It only applies in the languages it was defined as. How, you wonder? Let's take "fire".
Is that the original pronunciation of what we know as fire by the being that first mentioned it? We can 99.999999999999999% guarantee it is *not*. So. Is "fire" the incorrect word for fire? By the reasoning some want to apply, the answer is "yes." Which means, pretty much, no-one in he world knows what they are talking about and are speaking gibberish.
That is where we have "transliteration" and "translation". YHWH is incorrect. Why? The Tetragrammaton is *not written in modern Romanized characters.* YHWH is *not* God's name, *by any means.* 
It is an attempt to use existing character combinations with an aproximate sound to the word in another language. In the case of YHWH, this is even *more* incorrect, since the pronunciation is not being transliterated, but raw characters, whose pronunciation in that particular combination in their native language *no longer exists.* This brings us to "translation". To use an example, if you ever meet a Korean with the name "Lee", "Lee" is *not* his name. It is a *translation*. His real name, in accurate *transliteration* is "Ee". Lim is really "Him" without the "H" sound. Mr. Park has no "r" in his real name. I am sure you also have many examples.
Which, now, brings us back to Jehovah and English.
Until the time of Tyndale, no one had translated the original Hebrew texts into English. Yet, there is a word there that occurs about 7000 times, the concept and exact match of which the English language *does not have*.  Now, since *no one alive then or now* knows *how* that word is pronounced, Tyndale could have written Spongebob with a notation on the front that "Spongebob" is how he will represent the Tetragrammaton in his *translation*, because, with the pronunciation of the original *not known* he *cannot* transliterate. But, instead, he noticed that "Jeova" was being used elsewhere and why, so, rather than pick "Spongebob" he picked Jehovah (modern spelling. It was with an "i" before) and maintained some sort of reasoning for the translation.
And, of course, the reason Tyndale had to make a translation in the first place has its origins *with God.*
(ASV) Genesis 11:9 Therefore was the name of it called Babel; because Jehovah did there confound the language of all the earth: and from thence did Jehovah scatter them abroad upon the face of all the earth.
As God did not reveal His Name until *after* the Babel episode, those who eventually learned English *had no native concept* of the meaning of God's name, therefore no equivalent word to the Tetragrammaton. They would have to come up with them when they ran into the concept. And, when Tyndale did, he coined
"Jehovah" 
to represent the Hebrew Tetragrammaton in the English language about 500 years ago. And, this fact is attested to, still, in dictionaries:
British "Jehovah" in British English
 See all translations Jehovahnoun
 UK   /dʒəˈhəʊ.və/  US   /dʒəˈhoʊ.və/        › the name of God used in the Old Testament of the Bible http://dictionary.cambridge.org/dictionary/english/jehovah
Now, you can call out "Korean Dude!" or "Mr. Lee!". But, Mr. "Ee" will appreciate you using his name, which, in English, is Mr. "Lee."
And that is how we view Jehovah, which, in Korean, is Yohowah, which, in ancient Hebrew is . . . The Tetragrammaton. But, you can use Yahweh (or one of the 50 different variations claiming to be the True Pronunciation) if you want: It is *still* wrong. When the New Kingdom arrives for good, I am sure the True Name will be in wide use, and all will have the correct pronunciation. But, until then, we are left with Jesus's words at John 17:26
(CEB) I’ve made your name known to them and will continue to make it known so that your love for me will be in them, and I myself will be in them.”
And that is a *critical* reason to be using God's Name, *however* it may have been translated into the language *God Himself* gave you.

I agree. I still suspect there had to be a leap day adjustment especially since the "empty" moon was astronomically tied to March 28, 2017 in Jerusalem, so there is no way the first crescent would not be seen by March 29th. The full moon is on April 11th.
Note the article on wikipedia:
https://en.wikipedia.org/wiki/Days_of_week_on_Hebrew_calendar
Finally, in a regular year the month of Adar has 29 days, while in a leap year Adar I of 30 days is added before the regular Adar, which becomes Adar II of 29 days. The result is that the period from 1 Tevet to 29 Cheshvan is fixed, except that in a leap year Adar one of 30 days is added; and all adjustments are made using 30 Cheshvan and/or 30 Kislev.
The period from 1 Adar (or Adar II, in leap years) to 29 Cheshvan contains all of the festivals specified in the Bible - Purim(14 Adar), Pesach (15 Nisan), Shavuot (6 Sivan), Rosh Hashanah (1 Tishrei), Yom Kippur (10 Tishrei), Sukkot (15 Tishrei), and Shemini Atzeret (22 Tishrei). This period is fixed, during which no adjustments are made.
The result is that all dates from 1 Nisan through 29 (or 30) Cheshvan can each fall on one of four days of the week. Dates during Kislev can fall on any of six days of the week; during Tevet and Shevat, five days; and dates during Adar (or Adar I and II, in leap years) can each fall on one of four days of the week.
 
 

I see it now. They are listing the first full day, not starting from the evening before which would make our date on the equivalent of the start of Nisan 13. Probably the difference is because of the leap day adjustment so that Passover doesn't start on one of the three "forbidden" days of the week.

The 2017 Memorial is on April 11 not 10th. This is another year when our Nisan 14 is the Jewish Nisan 15.

Don't know why chabad.org appears to be off by a day, perhaps it's not set for the time in Israel/Jerusalem.

Brother Greenlees and Brother Chitty are not mentioned in the Proclaimer's book. Interesting that Percy Chapman (included in the picture above) is still mentioned now and then, often in the same context with Brother Greenlees. He was more "openly homosexual" to the dismay of Brother Knorr who continued to work with him anyway. I never knew that Brother Ewart Chitty was homosexual and assumed it was a rumor although I was told it was a fact by several. People also told me that Brother Greenlees was homosexual. In his case, there was good reason to believe them. But I never heard any facts for sure about the molestation charges, although it was a well-known rumor.
I should add, however, that there may be nothing wrong with trusting a homosexual brother to handle high levels of responsibility. The predisposition of someone should not disqualify them from responsibility as long as they can handle the responsibility without bringing reproach on Jehovah, on themselves, or others, and/or scandal upon the congregation. If a brother has already proven himself faithful and morally clean for many years, even if he struggles with sinful thoughts, then he is probably not so different from anyone else who was on the Governing Body at the time, even if these particular sins seem much more unexpected. Paul spoke of struggling with sin even as an apostle.

Probably the difference is because of the leap day adjustment so that Passover doesn't start on one of the three "forbidden" days of the week.

The above, from near the end of my last post should have started out, "From the time of the first Watchtower in 1879 until 1929, the only possible exceptions  . . . . "  (The other possible exceptions from 1929 until now had already been mentioned just above that.)
Just one more point to add is the fact that either method "Passover" or "Easter/Memorial" is consistent enough that you can always get the right date (within a day) by remembering that both methods "align" again every 19 years (Due to those 7 intercalary leap-months added every 19 years.) It's really amazing just how closely lunar 19 "lunar years" made up of 19 time 12 lunar months + 7 extra lunar months is almost exactly the same as 19 solar years.
You can check this by taking any year that we have had the memorial and dividing it by 19. If it divides evenly and the remainder is zero, then you can test every one of those years with the zero remainder and we will have the Memorial on that same day for each of those years. In fact it works for every possible remainder after dividing the year by 19.
For example, 2016 divided by 19 will have a remainder of 2. 19 years prior to that (1997 / 19) also has a remainder of 2, as does 1978 divided by 19, etc, etc. Look at the Memorial dates as announced in the Watchtower for each of these years:
1940: 3/23
1959 3/23
1978 3/23
1997 3/23
2016 3/23
You can almost always tell exactly what day the Memorial will be on by looking at what day it was on 19 years ago.

Paul spoke of struggling with sin even as an apostle.

There are lots of better places to get the full explanation, but here goes another attempt. Here's our typical expectation of the range of dates involved.
*** km 12/76 p. 3 Announcements ***
For future reference, you may wish to keep a record of local sunset times for the period of March 22 through April 19, 1977, since Memorial always falls within this period.
It's actually possible for this range to be expanded from March 21 through April 21 (although the one time we celebrated on March 20, 1932 we were not using our own criteria correctly). The Watchtower has determined dates outside of the range (1976 km) on five different occasions.
In 1948, the Watchtower said:
"1948 Memorial Date -   The date for celebrating the annual Memorial of Christ's death . . . is Nisan 14. . . . The Watch Tower Society calculates this according to the first new moon that falls nearest to the spring equinox, whether before it or after it. We do not follow strictly the fixed Jewish schedule of 7 intercalary months for every 19 year period."
In reality, this is about the same thing as saying the first FULL moon AFTER the vernal equinox, because the closest new moon to March 20/21 will result in a full moon observed about 13 to 15 days later. Therefore, we use the following method:
*** w76 2/1 p. 73 “Keep Doing This in Remembrance of Me” ***
According to our present method of calculation, the Memorial date approximates the nearest full moon after the spring equinox.
For easy calculation, let's say the equinox is always on 3/20 or 3/21, and you are looking for the nearest NEW moon before or after. You could get a new moon on 3/7 it could be slightly closer to 3/20 (13 days) than if the new moon was on 4/3 (14 days) after the equinox. Therefore, adding about 14 days to 3/7 gives us the earliest possible Memorial 3/21. For the latest possible Memorial, let's assume the equinox is on 3/21 that year, and the nearest new moon was determined to be 4/5. Adding 15 days to 4/5 could result in about the latest Memorial on 4/20.
Although our range for Nisan 14 is therefore 3/21 to 4/20, the Jewish Passover (Nisan 15) is celebrated between 3/26 and 4/30. Adjusting the Jewish calendar's range to Nisan 14 would mean 3/25 to 4/29. But that is still a range of about 35 days instead of 30 days. The reason is the timing of the leap-month, Adar II, (second Adar or Ve-Adar). The 1948 Watchtower said that we do not strictly follow the fixed Jewish schedule of 7 intercalary months for every 19 year period.
Of course, we actually do add 7 intercalary months for every 19 year period, but we don't do it on the same schedule the Jewish calendar uses. We did this until 1929, not necessarily by calculating it ourselves, but by watching what they used and subtracting a day or two for Nisan 14. But since 1929, we follow the same schedule that is used for determining the Easter season.
Easter Sunday generally falls on the Sunday following the Paschal Full Moon (i.e., the first full moon of Spring in the northern hemisphere, or the first full moon occurring after the date of the vernal equinox).
In 1929, 1932, 1948, 1951, 1959, 1967, 1970, 1978, 1986, 1989, 1997, 2002, 2005, 2008, 2010, and 2016 this method would result in being about 30 days ahead of the Jewish Passover season in each of those years. That's because the Jewish calendar added the leap-month in that very year, but we, in effect, followed a calendar that added it in the next year. This means that each of the years mentioned were the only years in that period where Easter and Passover were not aligned. Nisan 14 was 30 days earlier using the "Easter" calendar.
In every case, we followed the "Easter" calendar. (Not because it was "Easter" but because we use the same method.)
From the time of the first Watchtower in 1879, the only possible exceptions between Easter season and Passover season were in 1883, 1894, 1902, 1910, 1913, and 1921. (Easter and Passover were also about 30 days apart in those years.) In every one of those cases we did exactly the opposite. We always chose to follow the Jewish calendar for Passover.
In other words, in every year from 1880 to 1928 we always held Memorial within 3 days of the Jewish Passover. In every year from 1929 until now, including 2016 we have always held Memorial within the 8 day period prior to Easter.
 

Unwarranted acts often produce consequences that can't be fixed satisfactorily in this system. However, both sides can be humble and come to an agreement. Love conquer all things.

There are lots of better places to get the full explanation, but here goes another attempt. Here's our typical expectation of the range of dates involved.
*** km 12/76 p. 3 Announcements ***
For future reference, you may wish to keep a record of local sunset times for the period of March 22 through April 19, 1977, since Memorial always falls within this period.
It's actually possible for this range to be expanded from March 21 through April 21 (although the one time we celebrated on March 20, 1932 we were not using our own criteria correctly). The Watchtower has determined dates outside of the range (1976 km) on five different occasions.
In 1948, the Watchtower said:
"1948 Memorial Date -   The date for celebrating the annual Memorial of Christ's death . . . is Nisan 14. . . . The Watch Tower Society calculates this according to the first new moon that falls nearest to the spring equinox, whether before it or after it. We do not follow strictly the fixed Jewish schedule of 7 intercalary months for every 19 year period."
In reality, this is about the same thing as saying the first FULL moon AFTER the vernal equinox, because the closest new moon to March 20/21 will result in a full moon observed about 13 to 15 days later. Therefore, we use the following method:
*** w76 2/1 p. 73 “Keep Doing This in Remembrance of Me” ***
According to our present method of calculation, the Memorial date approximates the nearest full moon after the spring equinox.
For easy calculation, let's say the equinox is always on 3/20 or 3/21, and you are looking for the nearest NEW moon before or after. You could get a new moon on 3/7 it could be slightly closer to 3/20 (13 days) than if the new moon was on 4/3 (14 days) after the equinox. Therefore, adding about 14 days to 3/7 gives us the earliest possible Memorial 3/21. For the latest possible Memorial, let's assume the equinox is on 3/21 that year, and the nearest new moon was determined to be 4/5. Adding 15 days to 4/5 could result in about the latest Memorial on 4/20.
Although our range for Nisan 14 is therefore 3/21 to 4/20, the Jewish Passover (Nisan 15) is celebrated between 3/26 and 4/30. Adjusting the Jewish calendar's range to Nisan 14 would mean 3/25 to 4/29. But that is still a range of about 35 days instead of 30 days. The reason is the timing of the leap-month, Adar II, (second Adar or Ve-Adar). The 1948 Watchtower said that we do not strictly follow the fixed Jewish schedule of 7 intercalary months for every 19 year period.
Of course, we actually do add 7 intercalary months for every 19 year period, but we don't do it on the same schedule the Jewish calendar uses. We did this until 1929, not necessarily by calculating it ourselves, but by watching what they used and subtracting a day or two for Nisan 14. But since 1929, we follow the same schedule that is used for determining the Easter season.
Easter Sunday generally falls on the Sunday following the Paschal Full Moon (i.e., the first full moon of Spring in the northern hemisphere, or the first full moon occurring after the date of the vernal equinox).
In 1929, 1932, 1948, 1951, 1959, 1967, 1970, 1978, 1986, 1989, 1997, 2002, 2005, 2008, 2010, and 2016 this method would result in being about 30 days ahead of the Jewish Passover season in each of those years. That's because the Jewish calendar added the leap-month in that very year, but we, in effect, followed a calendar that added it in the next year. This means that each of the years mentioned were the only years in that period where Easter and Passover were not aligned. Nisan 14 was 30 days earlier using the "Easter" calendar.
In every case, we followed the "Easter" calendar. (Not because it was "Easter" but because we use the same method.)
From the time of the first Watchtower in 1879, the only possible exceptions between Easter season and Passover season were in 1883, 1894, 1902, 1910, 1913, and 1921. (Easter and Passover were also about 30 days apart in those years.) In every one of those cases we did exactly the opposite. We always chose to follow the Jewish calendar for Passover.
In other words, in every year from 1880 to 1928 we always held Memorial within 3 days of the Jewish Passover. In every year from 1929 until now, including 2016 we have always held Memorial within the 8 day period prior to Easter.
 

I see that the link was already shared. So as not to be misunderstood, contributions to that topic, including my own post, were not stating anything about how the "Society" calculates the the date of the Memorial. Most of the responses on that post dealt with the issue of being within one or two days in front of the Jewish Passover, and a discussion of whether or not Memorial could be scripturally interpreted as Nisan 15 instead of Nisan 14. There were some speculatory reasons that one might consider as to why the date for the Memorial could be a day or two off, but I don't think such reasons were ever taken into account by the "Society."  Those speculations are implied by some of the statements made in the Watchtower, but I don't believe they have ever been invoked -- especially not weather related visibility issues for the "new moon." This was not well explained, and if I still can, I might go back and edit that old post to make it clearer.
This question being discussed now is a bit different, anyway. It is about being one MONTH off from the Jewish Passover. Here, again, I think I was just throwing out some general ideas to offer a background to the reasons the lunar calendar needs adjustment to the solar calendar. The exact adjustments that are usually made, and formalized, include different methods from the ones I mentioned. I was speaking of the kinds of adjustments that we might make to the lunar calendar, including some leap days and leap months, that we, as JWs, could make, because we are not under the same constraints as the Jews are. (For example, certain months are sometimes given a leap day (or not) just so that the Passover can only fall on only one of 4 different options for allowable days of the week. (This is because there are certain activities within the several days of the Passover holiday season that can't fall on a Sabbath.) As JWs we could ignore some of these restrictions and make a much simpler determination of Nisan 14 through observation of the solar March equinox, and the determination of either the first full moon after that equinox or the one closest to that equinox.
In fact, however, even though the Watch Tower publications have mentioned some of the ideas I mentioned, they have never been factored in like that. If you were to look at the longest explanations about calculating the date (i.e., 1909, 1929, 1948, 1976, 2014, etc) you might think that observation had something to do with the date. In fact the dates were determined MONTHS in advance. Even the April 1976 date was already determined in print, and rolling off the presses in December 1975 (in the January 1976 km). Since the 1930's, the Watchtower usually printed the date 3 or 4 months in advance. The 2014 date, even though it was wrong, had already been determined in December 2012 in the Kingdom Ministry announcements.

The modern Jewish calendar determines the beginning of their month of Nisan by the astronomical new moon. However, usually it is eighteen hours or more later when the first sliver of the crescent of the new moon becomes visible in Jerusalem. Each year, in recent times, the governing body of Jehovah’s witnesses has determined the actual new moon that becomes visible in Jerusalem, which is the way the first of Nisan was determined in Biblical times. For this reason often there has been a difference of a day or two between the Memorial date of Jehovah’s witnesses and the Nisan 14 date according to the modern Jewish calendar.
According to our present method of calculation, the Memorial date approximates the nearest full moon after the spring equinox. . . . .The date for Memorial in 1976, calculated by our present method, falls on Wednesday, April 14, after sundown.
 
The issue in this question is about when it might be appropriate to add the "leap-month" to a different year than the Jewish custom might have chosen, either through an adjustment to the metonic cycle, or a calculation that makes sure Nisan 14/15 is either the first full moon after the spring equinox (or one that makes sure it is the one closest to the spring equinox. The only thing I believe we have ever done in this regard is, since 1929, to accept the earlier adjustment to the metonic cycle than the one that Jewish custom accepts.
Most of the time "Easter season" is within a week (between 1 and 8 days) of "Passover season."
This might surprise everyone, but as it turns out, we (WTS) ALWAYS accept an early "leap-month" when it will put our Memorial back in line with the Easter season and therefore a month prior to the Passover season. We ALWAYS reject the timing of the Jewish "leap-month" when it would put our Memorial in line ONLY with the Jewish Passover season. 
In other words, whenever Easter and Passover are NOT within a week of each other, they are about one month apart. Our calculation method means that we have NEVER missed putting our Memorial in the Easter season since 1929. Furthermore, prior to 1929, we ALWAYS matched Memorial to the Jewish Passover, 100% of the time, INSTEAD of choosing the Easter season, when Easter and Passover were not the same. 
There was ALMOST one exception. In 1913 (prior to 1929) we accidentally made a big mistake, where I think it's fairly obvious that we intended to match the date to the Jewish Passover season. We never matched it to Easter, instead, when we had the chance to choose. That  which was our custom every year for the prior 30 years. But we got the month wrong in 1913, and ended up having a Memorial that was even outside of the possible range of either Easter or Passover. 1913 was one of the earliest possible Easter dates that only comes around every hundred years or so, and we chose a date even prior to that.  It apparently fell on about Adar 12, instead of Nisan 14. The next month, the Watchtower printed a new date for the Memorial -- April 20, instead of March 20. The article said that if you already celebrated last month, you can go ahead and celebrate it again.

MEMORIAL 2014

  "The moon circles our earth each month. In the course of each cycle, there is a moment when the moon lines up between the earth and the sun. This astronomical configuration is termed “new moon.” At that point, the moon is not visible from the earth nor will it be until 18 to 30 hours later.

  "During 2014, the new moon nearest the vernal (spring) equinox will be on March 30, at 8:45 p.m. (20:45), Jerusalem time. The following sunset in Jerusalem (March 31) will come about 21 hours later. It is doubtful that the first sliver of the moon will be visible then. More likely, the first sunset when the initial crescent of the moon can be seen in Jerusalem will be on April 1. By the method the ancient Jews used, that will be the day when the first month (Nisan 1) will start, at sunset.
 
"Hence, congregations of Jehovah’s Witnesses around the earth have been informed that Nisan 14 will begin at sunset on Monday, April 14, 2014. That will be about the time of the full moon.—For more details on calculating the date, see The Watchtower of June 15, 1977, pages 383-384."

Correct date - new moon was on March 30.
Wrong time - new moon was at 21:45 Jerusalem time. The researcher hadn't factored in Daylight Saving Time that came in on March 28 for Israel.
Part in yellow:
Miscalculation of crescent visibility. Three astronomical programs calculated that the new crescent would be visible with the naked eye from Jerusalem on March 31. Granted, the crescent would be toward the limits of visibility criteria, but still would be theoretically possible to see according to,
the Planetary, Lunar and Stellar Visibility program (free download online) http://astro.ukho.gov.uk/moonwatch/index.html http://torahcalendar.com/MOON.asp?JDN=2457458&TDAY=1&MNFLG=0 Screenshots can be provided if you are that interested.
The Moon's crescent was indeed sighted in the vicinity of Jerusalem on March 31 as reported by this website.

Therefore, sunset March 31 was Nisan 1, and sunset April 13 (not 14) was Nisan 14. So JWs celebrated the 2014 Memorial on Nisan 15.
