The formula they use to determine Nisan 14 is;
Add fourteen days to the new moon nearest the spring equinox. Closest nwe moon to Spring equinox is on Feb 28 - so why did they not come up with March 14?
Mea Culpa - I was without glasses and clearly half-asleep when I wrote this.
Spring equinox is on March 20... duh. Was looking at wrong month.
New Moon following spring equinox is on March 29. [Which is also the new moon nearest the equinox, which is the way I recall the indoctrination, Scully. But I may have been incorrectly indoctrinated. LOL]
Fourteen days hence would be April 12. I am not sure if the day of the new moon was to be counted or not.
BTW - the Watchtower went to great lengths in one article to disprove the Jewish date of Passover as Nisan 15, though I do not recall the details.
Anyway, I apologize for not having me brain fully engaged before I posted this morning. Needed
