Watch out for False Feasts
Made up feasts
Exod.32:5 And when Aaron saw it, he built an altar before it; and Aaron made proclamation, and said, To morrow is a feast to the LORD.
1Kgs.12[32] And Jeroboam ordained a feast in the eighth month, on the fifteenth day of the month, like unto the feast that is in Judah, and he offered upon the altar. So did he in Bethel, sacrificing unto the calves that he had made: and he placed in Bethel the priests of the high places which he had made.
[33] So he offered upon the altar which he had made in Bethel the fifteenth day of the eighth month, even in the month which he had devised of his own heart; and ordained a feast unto the children of Israel: and he offered upon the altar, and burnt incense.
1Kgs.6[38] And in the eleventh year, in the month Bul, which is the eighth month, was the house finished throughout all the parts thereof, and according to all the fashion of it. So was he seven years in building it

A Made up feast not in the Bible
Judaism : Rosh Hashanah when the earth was made? NO!!! ( head of the Year - Rosh Hashanah.) Rosh Hashanah occurs on the first and second days of Tishri. There are no scriptures to back this up.

The Memorial Blowing of Trumpets, not rosh hashanah.
Bible says: Lev.23:[24] Speak unto the children of Israel, saying, In the seventh month, in the first day of the month, shall ye have a sabbath, a memorial of blowing of trumpets, an holy convocation.
[27] Also on the tenth day of this seventh month there shall be a day of atonement: it shall be an holy convocation unto you; and ye shall afflict your souls, and offer an offering made by fire unto the LORD.
[34] Speak unto the children of Israel, saying, The fifteenth day of this seventh month shall be the feast of tabernacles for seven days unto the LORD.
[39] Also in the fifteenth day of the seventh month, when ye have gathered in the fruit of the land, ye shall keep a feast unto the LORD seven days: on the first day shall be a sabbath, and on the eighth day shall be a sabbath.
[41] And ye shall keep it a feast unto the LORD seven days in the year. It shall be a statute for ever in your generations: ye shall celebrate it in the seventh month.
Num.29 [1] And in the seventh month, on the first day of the month, ye shall have an holy convocation; ye shall do no servile work: it is a day of blowing the trumpets unto you.
It is not Tishri, it is Ethanim
1Kgs.8 [2] And all the men of Israel assembled themselves unto king Solomon at the feast in the month Ethanim, which is the seventh month.
So you see by the scriptures:
1: Ethanim not Tishri
2: seventh month not First month
3: Blowing of Trumpets not Rosh Hashanah
... that simple! Exod.12[1] And the LORD spake unto Moses and Aaron in the land of Egypt, saying,[2] This month shall be unto you the beginning of months: it shall be the first month of the year to you.
Exod.13[1] And the LORD spake unto Moses, saying,[2] Sanctify unto me all the firstborn, whatsoever openeth the womb among the children of Israel, both of man and of beast: it is mine.
[3] And Moses said unto the people, Remember this day, in which ye came out from Egypt, out of the house of bondage; for by strength of hand the LORD brought you out from this place: there shall no leavened bread be eaten.[4] This day came ye out in the month Abib.
Lev.23 [5] In the fourteenth day of the "first month" at even is the LORD's passover. Deut.16[1] Observe the month of Abib, and keep the passover unto the LORD thy God: for in the month of Abib the LORD thy God brought thee forth out of Egypt by night.
