In reply to your 11/21 post REPLY TO: Donna Danna ( 14 Nov 2021 ) 1,260 days (fivedoves.com) about there always being 1,260 days from Nisan 10 to Tishri 1 & there being 1,270 days from Nisan 1 to Tishri 1, the link Moon Phases 2021 – Lunar Calendar for Jerusalem, Israel (timeanddate.com) at the bottom of your post doesn't say anything about 1,260 days nor 1,270 days.
My previous 11/14 post REPLY TO GARRY B. -- There ARE NOT ALWAYS 1,260 Days From Nisan 10 To Tishri 1 (3&1/2 Yrs. Later) (fivedoves.com)showed calculations for the next 5 yrs. that prove there are not always 1,260 days between Nisan 10 and Tishri 1. These calculations are based on the Hebrew or Jewish calendar which the Jewish people all over the world use to celebrate the Passover, the Feast of Trumpets, the Day of Atonement, & the Feast of Tabernacles. Their days of celebration would be off if they used your calculations of there always being 1,260 days from Nisan 10 to Tishri 1. No one is using your incorrect calculations on their Hebrew or Jewish calendar so I don't know why you keep on insisting that you are correct when you clearly are not.
