I think one is September 21st, thanking mother earth for the harvest. I don't know what the other one could be.
According to the Bible, the new moon this year is the same day. (Sept 21st, 2017 Hebrew month 7) This is the first day of trumpets in scripture.
Leviticus 23:22-24
[SUP]22 [/SUP]And when ye reap the harvest of your land, thou shalt not make clean riddance of the corners of thy field when thou reapest, neither shalt thou gather any gleaning of thy harvest: thou shalt leave them unto the poor, and to the stranger: I am the Lord your God.
[SUP]23 [/SUP]And the Lord spake unto Moses, saying,
[SUP]24 [/SUP]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.
Am I right about that one?
