In biblical reckoning, days begin in the evening (Genesis 1:5), when the sun goes down (Joshua 8:29; 2 Chronicles 18:34; Mark 1:32), and are counted “from evening to evening” (Leviticus 23:32). Thus, all God’s festivals begin the evening just before the dates listed in this table. For example, in 2004 Passover is observed Sunday evening, April 4, after sundown, and the Feast of Unleavened Bread begins Monday evening, April 5. The festivals end in the evening on the dates given.
