The Jewish holiday of Passover begins at sundown today and will focus this year on the war in Ukraine and political upheaval in Israel.

On the Jewish calendar, Passover begins on the 15th day of Nisan, which is typically in March or April. Passover commemorates the liberation of Jews from slavery in Egypt and the passing over of God's forces of destruction, sparing the Israelites' firstborn.

The first night of Passover is celebrated with a ritual dinner known as Seder.

Passover ends on April 13.
