Also in the day of your gladness and at your appointed feasts and at the new moon, you are to blow the trumpets over your burnt offerings and over the sacrifices of your peace offerings, and they will be to you for a memorial before your God. I am Yahweh your God.” Bible see other translations

“at the new moon.” Some versions read “at the beginning of your months,” that is, at the new moon. There was an established New Moon feast, just as there were other feasts and special days.
