Tonight begins the holiday of Passover. Other than Rosh Hashana and Yom Kipur, this is the one holiday that most Jews celebrate. (According to a study, while less than 1/4 of all Jews regularly [that means once a month, not once a week or once a day] attend synagogue, more than 70% attend a Pesach Seder.) Oh, Chanuka comes close, but most folks still don’t light the menora.
