In your 11/07 post A LITTLE KNOWN FACT THAT YOU SHOULD KNOW (fivedoves.com) you stated, "It is a little-known IMPORTANT FACT that there are ALWAYS 1,260 days from Nisan 10, of EVERY YEAR , to Tishri 1, 3 1/2 years later , and Tishri 1, is ALWAYS the Feast of Trumpets ."
You also stated the following:
From Nisan 10, 2022 to Tishri 1, 2025 which is the Feast of Trumpets that falls on Tuesday September 23, 2025
However, it is incorrect to believe that there are always 1260 days from Nisan 10 to Tishri 1, 3 & 1/2 years later with Tishri 1 being the 1st day of the Feast of Trumpets.

Nisan 10, 2022 falls on Mon. April 11 and not on April 12 as you indicated above. Please see the Jewish calendar for the year 2022 at Jewish Calendar 2022 Diaspora | Hebcal and at the holidays at the bottom of the calendar at Year 2022 Calendar – Israel (timeanddate.com) They both say Nisan 10 is on Mon. April 11. There are 31 days in Jan. of 2022, 28 days in Feb., 31 days in March + 10 days in April (before Apr. 11) which total 100 days & it leaves 265 days remaining in 2022 from Apr. 11 (Nisan 10) thru Dec. 31, 2022. The 265 days left in 2022 + 365 days in 2023 + 366 days in 2024 +265 days in 2025 = 1,260 days. The 265th day of 2025 is Sept. 21, 2025 which is Elul 28 & Tishri 1 is on Sept. 23, 2025. There is 1 additional day Elul 29 Eve of the Feast of Trumpets before Tishri 1, but not including Tishri on Sept. 23, 2025. Therefore, there are 1,261 days from Nisan 10, April 11, 2022 thru Elul 29 on Sept. 22, 2025 which is the Eve of the Feast of Trumpets, but not including Tishri 1, the Feast of Trumpets.

Nisan 10, 2023 falls on 4/01/2023 as you stated. There are 31 days in Jan., 28 days in Feb., & 31 days in March = 90 days + 275 remaining days in 2023 from April 1 (Nisan 10) to Dec. 31, 2023. The 275 days left in 2023 + 366 days in 2024 + 365 days in 2025 + 254 days in 2026 = 1,260 days. The 254th day of 2026 is Sept. 11 which is the Eve of the Feast of Trumpets so there are 1,260 days from 4/01/2023 (Nisan 10) thru 9/11/2026 which is the Eve of the Feast of Trumpets with the Feast of Trumpets falling on Tishri 1, 9/12/2026.

The 272nd day of 2027 is 9/29 which is Elul 27 with the Eve of the Feast of Trumpets on Elul 29 which is 10/01/2027 & Tishri 1, the Feast of the Trumpets on 10/02/2027.

The 279 remaining days in 2026 + 365 days in 2027 + 366 days in leap yr. 2028 + 250 days in 2029 = 1,260 days.
