So a harpazo or a raising up on the last day of those who believe in Him was possibly what Jesus was talking about in John 6:40 (as well as in 6:39, 6:44, and 6:54). If the last day is Oct. 8-9, 2020 Hoshana Rabbah (the last day), it is exactly 2,550 days (1,290 + 1,260) until Oct. 2, 2027, the Feast of Trumpets. Daniel 12:11 mentions that from the time the daily sacrifice is taken away until the abomination of desolation it is 1,290 days. I'm assuming that the daily sacrifice "taken away" is the time of the rapture (Oct. 8), so perhaps there is a gap of 30 days from the rapture until the Tribulation begins or Nov. 7, 2020, which makes the Tribulation 2,520 days (1,260 + 1,260) or 7 years, or divided in half 3.5 years. So the Tribulation would be from Nov. 7, 2020 to October 2, 2027
