Two of these dates are especially prominent: 1 Nisan is the ecclesiastical new year, i.e. the date from which months and festivals are counted.Hebrew-English Bible, "This month [Aviv/Nisan] shall be unto you the beginning of months; it shall be the first month of the year to you." Thus Passover (which begins on 15 Nisan) is described in the Torah as falling "in the first month",Hebrew-English Bible, while Rosh Hashana (which begins on 1 Tishrei) is described as falling "in the seventh month".Hebrew-English Bible, 1 Tishrei is the civil new year, and the date on which the year number advances. This date is known as Rosh Hashanah (lit. "head of the year"). Tishrei marks the end of one agricultural year and the beginning of another,Hebrew-English Bible, , and thus 1 Tishrei is considered the new year for most agriculture-related commandments, including Shmita, Yovel, Maaser Rishon, Maaser Sheni, and Maaser Ani.
