This year's Hanukkah celebration is quite unique! How so? Hanukkah is observed on the 25th day of Kislev in the Hebrew calendar. The Hebrew and Gregorian calendars don't exactly line up, meaning Hanukkah can fall between late November and late December. This year Hanukkah begins on December 25th with the 8th day landing on January 2nd! How cool is that?!
