What all does the Passover holiday entail? A friend of mine is Jewish and I want to be respectful of the holiday and would like to know how best to do that.
The most fundamental aspect of the holiday is that no form of leaven can be eaten or even owned by Jews. Leavening occurs when dough is able to rise. So, all foodstuffs that Jews eat during this holiday have to certified by rabbis that they are free of leaven.
Otherwise, the holiday involves additional synagogue services and, of course, the seder on the first two nights.
