Tishrei (/ˈtɪʃreɪ/) or Tishri (/ˈtɪʃriː/; Hebrew: תִּשְׁרֵיtīšrē or תִּשְׁרִי tīšrī; from Akkadiantašrītu "beginning", from šurrû "to begin") is the first month of the civil year (which starts on 1 Tishrei) and the seventh month of the ecclesiastical year (which starts on 1 Nisan) in the Hebrew calendar. The name of the month is Babylonian. It is a month of 30 days. Tishrei usually occurs in September–October on the Gregorian calendar.
In the Hebrew Bible the month is called Ethanim (Hebrew: אֵתָנִים – 1 Kings 8:2), or simply the seventh month. In the Babylonian calendar the month is known as Araḫ Tišritum, "Month of Beginning" (of the second half-year).
