The Last Trump and the 7th Trumpet Judgment are the same. "Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed, 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" (1Corinthians 15:51-52). This trumpet blast takes place 8 days prior to the last day of the Tribulation Week. How so? Since: (1) the Last Trump is sounded on Rosh HaShanah on Tishri 1, (2) the Second Coming of Jesus Christ takes place on the Day of Atonement (Yom Kippur), which is Tishri 10, and (3) the last day of the Tribulation Week is Tishri 9 -- because Jesus will return "immediately after the tribulation of those days [Tishri 10]" (Matthew 24:29), then the Last Trump must sound 8 days prior to the end of the Tribulation Week.
