Passover is a festival of freedom. It commemorates the Israelites’ Exodus from Egypt, and their transition from slavery to freedom. The main ritual of Passover is the seder, which occurs on the first two night (in Israel just the first night) of the holiday — a festive meal that involves the re-telling of the Exodus through stories and song and the consumption of ritual foods, including matzah and maror (bitter herbs). The seder’s rituals and other readings are outlined in the Haggadah — today, many different versions of this Passover guide are available in print and online, and you can also create your own.

The central Passover practice is a set of intense dietary changes, mainly the absence of hametz, or foods with leaven. (Ashkenazi Jews also avoid kitniyot, a category of food that includes legumes.) In recent years, many Jews have compensated for the lack of grain by cooking with quinoa, although not all recognize it as kosher for Passover. The ecstatic cycle of psalms called Hallel is recited both at night and day (during the seder and morning prayers). Additionally, Passover commences a 49-day period called the Omer, which recalls the count between offerings brought to the ancient Templein Jerusalem. This count culminates in the holiday of Shavuot, the anniversary of the receiving of the Torah at Sinai.

Passover 2019 begins at sundown on Friday, April 19, and ends Saturday evening, April 27. The first Passover seder is on the evening of April 19, and the second Passover seder takes place on the evening of April 20.
