Chanukkah (or Hanukkah) is the Jewish Festival/Feast of Dedication, also known as the "Festival of Lights.” It is an eight-day festival beginning on the 25th day of the Jewish month of Kislev, which typically falls in November or December on our calendar. Although this Jewish festival in not mentioned in the Tanakh (the Hebrew Bible), it is referenced in the Talmud: “On the 25th of Kislev are the days of Chanukkah, which are eight... these were appointed a Festival with Hallel [prayers of praise] and thanksgiving” (Shabbat 21b, Babylonian Talmud).
