"Rejoice in your festivals!" the Torah tells us. "Just be happy!" But which festivals? The Jewish calendar contains four biblical festivals: Passover, Shavuot, Sukkot and Shemini Atzeret (Simchat Torah), each containing a unique message and distinct rules. What they all have in common, however, is:
- We honor them by wearing our finest wardrobe and baking our best challah.
- We enjoy them by serving great meals–even better than Shabbat. We dine twice a day, nighttime and daytime, following a kiddush and challah, with meat (if you enjoy meat) and delicacies.
- We rejoice in them by giving the children treats, buying our wives fine clothes and jewelry (each husband according to his means) and drinking wine, as is written, "Wine rejoices the hearts of men." We also try our best to have guests, especially guests that may otherwise not be so happy–like the widow, the orphan, the immigrant and the impoverished and otherwise downtrodden.
- Women and girls light candles to usher in each holiday eve. Special holiday prayers are recited.
Rosh Hashanah is also a holiday, but not a festival–so A, B and D apply, but not C.
Almost all activities forbidden on Shabbat are forbidden on festivals; e.g., operating an electric gadget, going to work, driving, writing or handling money. There are exceptions. Here are some permitted activities:
- Most activities necessary for food preparation, e.g., kneading, baking, and cooking (on a stove that has been left on since the onset of the holiday).
- Lighting a fire from a pre-existing flame.
- Carrying in the public domain.

All the above applies to the first two and last two days of Passover, both days of Shavuot, the first two days of Sukkot and the two days of Shemini Atzeret and Simchat Torah. (Different, far more lenient rules apply to Passover’s and Sukkot’s "Intermediate Days.")
