The eight-day Jewish celebration known as Hanukkah or Chanukah commemorates the rededication during the second century B.C. of the Second Temple in Jerusalem, where according to legend Jews had risen up against their Greek-Syrian oppressors in the Maccabean Revolt. Hanukkah begins on the 25th of Kislev on the Hebrew calendar and usually falls in November or December. Hanukkah 2022 begins on the evening of Sunday, December 18 and ends on the evening of Monday, December 26.
