In the King James Version of the Bible, the “Memorial of Blowing of Trumpets” is referred to as the Feast of Trumpets or the Day of Trumpets. It is one of the biblical festivals or holy convocations observed by the Israelites, as outlined in the Old Testament.

The Feast of Trumpets is described in the book of Leviticus, specifically in Leviticus 23:23-25:

“And the Lord spake unto Moses, saying, 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. Ye shall do no servile work therein: but ye shall offer an offering made by fire unto the Lord.”

According to the biblical instructions, the Feast of Trumpets is to be observed on the first day of the seventh month of the Hebrew calendar (Tishrei), which generally falls in September or October. It is considered a sacred day, a Sabbath, and a holy convocation or gathering together for worship.

The blowing of trumpets or shofars (a type of horn made from a ram’s horn) was a significant element of this observance. It was used to announce the beginning of the festival and to signal its importance. The blowing of the trumpets held symbolic meanings, including summoning the people to battle and for rejoicing.  It has its ultimate fulfillment on the Day of the Lord.
