In Judaism there are 4 different New Year days.
In Judaism, we mark the different “new years” like this:
The 1st of the month of Nissan (March/April) kicks off the holiday cycle and the month of Nissan is considered to the first month of the year. Yes, that’s right, Rosh Hashanah is explained in the Torah as the 1st of the 7th month of the year. During the month of Nissan, we celebrate Pesach (Passover), which marks the beginning of spring and commemorates the traditional story of the exodus from Egypt and the rebirth of the Jewish people. Definitely feels like the beginning of a year as well!
The 1st of the month of Elul (usually in August) is the new year for the animals.
Tu B’Shevat (January/February) is the new year for trees (determines when first fruits can be eaten).
The 1st of Tishrei (Rosh Hashanah) is the new year for years (when we increase the year number).
