'Appointed Feasts' in the Bible

Also in the day of your gladness and in your appointed feasts, and on the first days of your months, you shall blow the trumpets over your burnt offerings, and over the sacrifices of your peace offerings; and they shall be as a reminder of you before your God. I am the Lord your God.”

‘You shall present these to the Lord at your appointed times, in addition the offerings you have vowed and your freewill offerings, as your burnt offerings, grain offerings, drink offerings, and as your peace offerings.’”
