Note that all Jewish holidays begin the evening before the date specified  on most calendars. This is because a Jewish "day" begins and ends at sunset,  rather than at midnight

Hanukkah — Festival of Lights. It commemorates the Maccabean recapture and rededication of the Jerusalem Temple in 165-164 b.c.e. Special readings and praise songs focus on liberty and freedom. The eight candle Menorah is lighted

Rosh Hashanah — Jewish New Year. A time of introspection, abstinence, prayer and penitence. The story of Abraham is read, the ram's horn is sounded, and special foods are prepared and shared. Avoid scheduling important academic deadlines, events or activities. Food accommodations should be made for events.

Passover — 8-day celebration of the deliverance of the Jews from slavery in Egypt. The story of the Exodus is recounted, and the ongoing struggle of all peoples for freedom from internal and external tyranny is celebrated. A special meal is a central feature. Also called Pesach. Avoid scheduling important academic deadlines, events or activities. Food accommodations should be made for events. Besides Kosher restrictions, the use of leavening is prohibited; matzah is eaten in place of bread.

Purim — celebration of the deliverance of the Jewish minority in Persia from genocide. Charity to the poor, sharing food with friends, and vigorous merrymaking mark the observance.
