All Feast Days begin at sundown and end at sundown on the day specified in your location.

Exodus 12:14-20

14 And this day shall be unto you for a memorial; and ye shall keep it a feast to Yah throughout your generations; ye shall keep it a feast by an ordinance for ever.

15 Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses: for whosoever eateth leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.

16 And in the first day there shall be an holy convocation, and in the seventh day there shall be an holy convocation to you; no manner of work shall be done in them, save that which every man must eat, that only may be done of you.

17 And ye shall observe the feast of unleavened bread; for in this selfsame day have I brought your armies out of the land of Egypt: therefore shall ye observe this day in your generations by an ordinance for ever.

18 In the first month, on the fourteenth day of the month at even, ye shall eat unleavened bread, until the one and twentieth day of the month at even.

19 Seven days shall there be no leaven found in your houses: for whosoever eateth that which is leavened, even that soul shall be cut off from the congregation of Israel, whether he be a stranger, or born in the land.

20 Ye shall eat nothing leavened; in all your habitations shall ye eat unleavened bread.

Leviticus 23:4-8

4 These are the feasts of Yah, even holy convocations, which ye shall proclaim in their seasons.

5 In the fourteenth day of the first month at even is Yah’s passover.

6 And on the fifteenth day of the same month is the feast of unleavened bread unto Yah: seven days ye must eat unleavened bread.

7 In the first day ye shall have an holy convocation: ye shall do no servile work therein.

8 But ye shall offer an offering made by fire unto Yah seven days: in the seventh day is an holy convocation: ye shall do no servile work therein.
