'Months' in the Bible

"Also in the day of your gladness, and in your set feasts, and in the beginnings of your months, you shall blow the trumpets over your burnt offerings, and over the sacrifices of your peace offerings; and they shall be to you for a memorial before your God. I am Yahweh your God."

"'In the beginnings of your months you shall offer a burnt offering to Yahweh: two young bulls, and one ram, seven male lambs a year old without blemish;

Their drink offerings shall be half a hin of wine for a bull, and the third part of a hin for the ram, and the fourth part of a hin for a lamb: this is the burnt offering of every month throughout the months of the year.
