Was the first Sukkot celebrated more than five months after the children of Israel left the land of Egypt? I ask this because Sukkot is celebrated in Tishrei which is the seventh month in the Hebrew calendar. Did the Lord take the children of Israel out of the land of Egypt in the month of Nisan, in the year 2448 from creation and then have the children of Israel live in booths for the first time ever in the month of Tishrei in the year 2,448 from creation?
Upon examination, we see that the holiday of Sukkot and all of her details (the mitzvah to live in temporary dwellings, taking the 4 species, cessation of work on the first and eighth days, are all mentioned in the book of Vayikra (Leviticus) ch. 23 which was given to Israel at the Ohel Moed (the Mishkan), in the first year after the exodus from Egypt. Accordingly, even the opinion which says that not all of the Torah was given in the first year in the desert, agrees that the holiday of Sukkot was.
