Dear Donna,

 

To accurately determine the number of days between  Nisan 10 of any particular year and the Feast of Trumpets 42  months in advance you first  need to know that the Feast of Trumpets is the ONLY Feast of the Lord that ALWAYS falls on a New Moon Day which is ALWAYS Tishri 1 of EVERY year which makes it a benchmark date from which to calculate . Every New  Moon Day is charted by  NASA for many years into the future. To find the date of Nisan 10 for any particular year you must first find the date of the New  Moon of Tishri 1 , Feast of Trumpets 42 months in advance , and  then calculate backwards 1,260 days from that  benchmark date to find the date of Nisan 10.  

 

According to the NASA  chart for Jerusalem the New  Moon of Tishri 1, 2024 falls on October 2, 2024 @ 9:49 pm which then makes October 3, 2024 Tishri 1, Feast of Trumpets.

By using the Easy Surf computerized day counter you will then find that from April 22. 2021 as day #1 TO BUT NOT INCLUDING  October 3, 2024 there  are EXACTLY 1,260 days from Nisan 10 TO the Feast of Trumpets. Because the Hebrew days  begin and end at sunset Nisan 10, 2021 will begin at sunset April 21, 2021 and end at sunset April 22, 2021. Likewise the Feast of Trumpets 1,260 days later will begin at sunset October, 2, 2024. October 3, 2024 is the Feast of Trumpets fully come. 

 

To double check my work I looked up the NASA New Moon date for Nisan 1, 2021 in April 2021 and found it to fall on April 12, 2021 @ 5:30 am. Therefore 10 days later is Nisan 10, 2021 which falls on  April 22, 2021. There are ALWAYS 1,260 days from Nisan 10 of every year to the New Moon of Tishri 1, 42 months later on the Feast of Trumpets.

 

Come Lord Jesus !
