Why does hunakuh start on a dfferent day every year?

Answer 1

Hanukkah starts on a different day each year because it follows the Hebrew calendar, which is lunar-based, rather than the Gregorian calendar, which is solar-based. Specifically, Hanukkah begins on the 25th of Kislev, the ninth month of the Hebrew calendar, resulting in its date varying between late November and late December in the Gregorian calendar. This shift occurs because the Hebrew calendar is about 11 days shorter than the Gregorian calendar.
