1Co 15:52 In 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
It's the same event as this:
Rev 11:15 And the seventh angel sounded (-the trumpet); 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.
As pointed out in the article, all prophetic and major events occur on the holy days that God created. For example, the holy spirit first came upon man at Pentecost. This is no coincidence, but part of God's prophetic plan. God made his holy days to help us understand them.
Thanks Douglas,
