Hanukkah (IPA: /ˈhænəkə/, /ˈhɑːnəkə/; Hebrew: חֲנֻכָּה, romanized: Ḥănukkā, lit. 'dedication'; ) is a Jewish holiday that commemorates the Maccabean Revolt against the Seleucid Empire in the 2nd century BCE, when the Maccabees successfully recovered Jerusalem and the Second Temple.
Beginning on the 25th of Kislev on the Hebrew calendar, Hanukkah lasts for eight nights and days. Each night is marked by lighting a Hanukkah menorah, a nine-branched candelabrum containing spaces for eight ceremonial lights plus one additional candle, the shámash (שַׁמָּשׁ, 'attendant'), which is used to light the others. Aside from the shamash, one candle is lit on the first night, two on the second, and so on, until all eight are burning together on the final night. It is the only Jewish holiday that starts in one month (Kislev) and concludes in another (Tevet) of the Hebrew calendar.
