Passover (called Pesach in Hebrew) is one of the most important holidays in Judaism. It commemorates the escape of the Jews from slavery in Egypt, and is celebrated annually either in March or April, depending on the dates in the Hebrew Calendar. The main themes highlighted in the seder ritual feast are freedom, redemption and thankfulness. If you want to celebrate Passover as someone new to Jewish customs, start by preparing properly for the Passover celebration and following the right customs when you attend the Passover meal. You can also celebrate Passover in other ways with movies or books if you cannot attend the traditional meal.
