'Occasions' in the Bible

You are to sound the trumpets over your burnt offerings and your fellowship sacrifices and on your joyous occasions, your appointed festivals, and the beginning of each of your months. They will serve as a reminder for you before your God: I am Yahweh your God.”

Since Balaam saw that it pleased the Lord to bless Israel, he did not go to seek omens as on previous occasions, but turned toward the wilderness.

After that, they offered the regular burnt offering and the offerings for the beginning of each month and for all the Lord’s appointed holy occasions, as well as the freewill offerings brought to the Lord.
