From sundown on Monday, December 14 to nightfall on Tuesday, December 15, 1964. 10 Tevet 5725 · עשרה בטבת Tenth of Tevet (Hebrew: י' בטבת), or Asarah BeTevet (pronounced [a.saˈra be.teˈvet]; עשרה בטבת), is the tenth day of the Hebrew month of Tevet and a fast day (Ta'anit) in Judaism. It is the only minor fast observed even on the Friday preceding Shabbat (Erev Shabbat)—on which fasting is typically prohibited—from before dawn to nightfall (or Kiddush); other fast days are postponed until Shabbat ends. The fast mourns the 587 BCE siege of Jerusalem by Nebuchadnezzar II of Babylonia—an event that began on Tevet 10 and culminated in the destruction of Solomon's Temple (i.e., the First Temple), the downfall of the Kingdom of Judah, and the Babylonian exile of the Judeans. The fast day is not usually thought to be related to Hanukkah, but it falls a week after the end of that festival. Whether the 10th of Tevet occurs seven or eight days after the last day of Hanukkah depends on whether the preceding Hebrew month of Kislev has 29 or 30 days in the given Hebrew year.
