Question: what is the difference between passover and the feast of unleavened bread?
Answer: The Feast of Unleavened Bread is to start on the 15th day of Nisan, the same month as Passover, at twilight. This is a 7-day feast and the first and last days are to be Sabbaths. These Sabbaths differ from the weekly Sabbath (Saturday) and may occur on any day of the week.
