Tevet is the tenth month of the Hebrew calendar, typically falling in December and January. It is a winter month in the Northern Hemisphere and has 29 days. Tevet is significant in Jewish tradition, as it includes the fast day of Asarah B'Tevet, which commemorates the siege of Jerusalem by the Babylonians. During Tevet, the days gradually become longer as the winter solstice passes. The month is often associated with themes of reflection and renewal, as it occurs during a time of introspection in the Jewish calendar, following the festive month of Kislev.
