Hanukkah in Modern Hebrew; a transliteration also romanized as Chanukah or Chanukkah, also known as the Festival of Lights and Feast of Dedication, is an eight-day Jewish holiday commemorating the rededication of the Holy Temple (the Second Temple) inJerusalem at the time of theMaccabean Revolt against the Seleucid Empire of the 2nd century BCE. Hanukkah is observed for eight nights and days, starting on the 25th day of Kislev according to the Hebrew calendar, which may occur at any time from late November to late December in the Gregorian calendar.
The festival is observed by the kindling of the lights of a unique candelabrum, the nine branched Menorah or Hanukiah, one additional light on each night of the holiday, progressing to eight on the final night. The typical Menorah consists of eight branches with an additional raised branch.
The extra light is called a shamash (Hebrew: שמש, “attendant”) and is given a distinct location, usually above or below the rest. The purpose of the shamash is to have a light available for practical use, as using the Hanukkah lights themselves for purposes other than publicizing and meditating on the Hanukkah is forbidden.
