Got it. You didn’t explain it at all, but Wikipedia provided a decent summary:
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.[23] Thus Passover (which begins on 15 Nisan) is described in the Torah as falling “in the first month”,[24] while Rosh Hashana (which begins on 1 Tishrei) is described as falling “in the seventh month”.[25]
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,[26] and thus 1 Tishrei is considered the new year for most agriculture-related commandments, including Shmita, Yovel, Maaser Rishon, Maaser Sheni, and Maaser Ani.
