March 25th used to be the new year.

[peterlindner]

So the last shall be first, and the first last. March 25th is the first of the year. March 25th is adar 29th which is the last day of the Hebrew year.

 

[ViaCrucis]

So the last shall be first, and the first last. March 25th is the first of the year. March 25th is adar 29th which is the last day of the Hebrew year.

The Jewish calendar is a lunisolar calendar, the Julian and Gregorian calendars are solar calendars. The dates on the Jewish calendar will be different, year to year, from either the Gregorian or Julian calendars.

The 29th of Adar lands on the 25th of March in 2020. Last year in 2019, the 29th of Adar landed on the 6th of March. In 2021 it will land on the 13th of March.

These dates are in the Gregorian calendar.

Under the original Julian calendar the new year was January 1st. In the middle ages the new year shifted to several different dates, including March 25th. So, there were times when March 25th was celebrated as the new year under the Julian calendar during the middle ages. However, with the Gregorian calendar reform the new year was restored back to January 1st. Thus the Gregorian calendar has always had January 1st as the new year.

Regardless of whether we use the Gregorian calendar or if we were to use the Julian calendar, there would always be a discrepancy between it and the Jewish calendar, because the way the year is calculated is different.

Even further, the Jewish new year is Rosh Hoshanna (or Yom Teruah), and it happens on the 1st of Tishrei, which in 2020 falls on September 19th. Religiously, for the purpose of festivals, the 1st of Nisan is counted as the first year. For the purpose of calculating the start of the year, Rosh Hoshanna on the 1st of Tishrei is used; for the purpose of calculating the new cycle of holy days the 1st of Nisan is used.
