The fourth festival of God (after Pentecost) is the Feast of Trumpets (or a “memorial of blowing of trumpets,” Leviticus 23:24-25 Leviticus 23:24-25  Speak to the children of Israel, saying, In the seventh month, in the first day of the month, shall you have a sabbath, a memorial of blowing of trumpets, an holy convocation.
 You shall do no servile work therein: but you shall offer an offering made by fire to the LORD.
American King James Version×), which falls in September or October. This festival is called Rosh Hashanah by the Jews today. Ancient Israel understood that trumpets were used as a way of announcing special, very important messages (Numbers 10:1-10 Numbers 10:1-10  And the LORD spoke to Moses, saying,  Make you two trumpets of silver; of a whole piece shall you make them: that you may use them for the calling of the assembly, and for the journeying of the camps.  And when they shall blow with them, all the assembly shall assemble themselves to you at the door of the tabernacle of the congregation.  And if they blow but with one trumpet, then the princes, which are heads of the thousands of Israel, shall gather themselves to you.  When you blow an alarm, then the camps that lie on the east parts shall go forward.  When you blow an alarm the second time, then the camps that lie on the south side shall take their journey: they shall blow an alarm for their journeys.  But when the congregation is to be gathered together, you shall blow, but you shall not sound an alarm.  And the sons of Aaron, the priests, shall blow with the trumpets; and they shall be to you for an ordinance for ever throughout your generations.  And if you go to war in your land against the enemy that oppresses you, then you shall blow an alarm with the trumpets; and you shall be remembered before the LORD your God, and you shall be saved from your enemies.  Also in the day of your gladness, and in your solemn days, and in the beginnings of your months, you shall blow with the trumpets over your burnt offerings, and over the sacrifices of your peace offerings; that they may be to you for a memorial before your God: I am the LORD your God.

In the New Testament, Jesus Christ reveals that before His return to the earth, there will be the blowing of seven trumpets, announcing progressive stages of the downfall and overthrow of this world’s kingdoms, ending with the return of Christ to take possession of the earth. Christ’s return is announced by the seventh and final trumpet (Revelation 8:2 Revelation 8:2And I saw the seven angels which stood before God; and to them were given seven trumpets.
American King James Version×; Revelation 11:15 Revelation 11:15And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever.

This day also pictures the time when faithful Christians will be resurrected to eternal life at the time of the seventh trumpet (1 Corinthians 15:52 1 Corinthians 15:52In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
American King James Version×; 1 Thessalonians 4:16 1 Thessalonians 4:16For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:

But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection.  Blessed and holy is he that has part in the first resurrection: on such the second death has no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.

Interestingly, it was around this time of year that Jesus was born—not in the dead of winter (see “Biblical Evidence Shows Jesus Wasn’t Born on December 25”). And the fall feast season represents the time when Jesus Christ will come to the earth again to reign in glory.
The remaining fall feast days describe steps in the establishment of the prophesied Kingdom of God on earth and judgment of humanity after Christ’s return. The Feast of Trumpets is followed by the Day of Atonement.
