Four Jewish New Years: Why Rosh Hashanah is Celebrated Now

While most Jews today associate Rosh Hashanah with the first day of the Hebrew month of Tishrei, the Jewish tradition recognizes four distinct dates that serve as "New Years." Each of these dates historically marked a different beginning, related to various aspects of Jewish life, from royal succession to agricultural cycles.

The concept of multiple New Years originates in the Mishnah, a foundational text of Rabbinic Judaism. The Mishnah identifies four New Years: Nisan 1, Elul 1, Tishrei 1, and Tu B'Shvat. Nisan 1 was considered the New Year for kings and festivals. Elul 1 marked the New Year for the tithing of cattle, determining which year animals belonged to for tithe purposes. Tu B'Shvat, now known as the "New Year for Trees," was originally designated as such.

Tishrei 1, however, evolved to become the most significant and widely recognized Rosh Hashanah. It served as the New Year for the counting of years, the Sabbatical year (Shmita), the Jubilee year, and also for plantings and vegetables. This date signified the start of a new year across multiple crucial domains.

The reason Tishrei 1 became the primary Rosh Hashanah is not because it superseded the others, but because it marked the transition of the year itself. While Nisan was important for counting regnal years and festival cycles, and Tu B'Shvat for the agricultural cycle, Tishrei represented the overarching annual transition. Over time, concepts of judgment, introspection, and new beginnings became associated with this date, further solidifying its central role.

Adding to potential confusion, Tishrei is referred to as the "seventh month" in the Torah, as the Hebrew calendar traditionally begins its month count with Nisan. However, Tishrei 1 marks the start of the year for counting years and for the Shmita and Jubilee cycles, thus resolving the apparent contradiction. Today, Tishrei 1 is the public and festive Rosh Hashanah, accompanied by traditions like the sounding of the shofar, special prayers, and themes of judgment and repentance, while the other New Years continue to hold their specific, albeit less universally celebrated, significance.
