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).
7 Tishrei (c. 1313 BCE) – Taanit tzaddikim (Orach Chaim 5580:2) commemorating God's decree that the Dor Hamidbar die in the wilderness because of the sin of the Eigel HaZahav / Golden Calf (according to some, (Kol Bo and others), the event took place one day earlier, on 6 Tishrei).
9 Tishrei (123 CE) – Death of the Tanna R' Elazar ben Rab' Shimon.
10 Tishrei (c. 1313 BCE) – Moses returns from a final trip to Mount Sinai, bearing a second set of tablets and a message of forgiveness for the Golden Calf. [citation needed]
11 Tishrei – The Baal Shem Tov wrote that the day after Yom Kippur is an even greater holiday than Yom Kippur itself, a day called "Bshem HaShem" or in Yiddish "Gott's Nomen", literally "The Name of God".
Tishrīn (Arabic: تشرين) is the name of two Gregorian months in the Levant:
Tishrīn al-Awwal (Arabic: تشرين الأول, literally "First Tishrin"): October. The 1973 Yom Kippur War is generally known by the name Ḥarb Tishrīn ("October War") in Syria and Lebanon, and among the Palestinians, following the Arab custom of naming the Arab-Israeli wars by months or years.
Tishrīn al-Thāni (Arabic: تشرين الثاني, literally "Second Tishrin"): November.
