There are 2300 days from the 4th day inspection of the lamb to Tisha B'Av when there are 2,520 days from Feast of Trumpets to Tisha B'Av. Since the Temple is cleansed when Jesus returns, He must return on Tisha B'Av and not on the 2550th day in years when the 2550th day lands on Day of Atonement. How can the Temple be cleansed when Armageddon is still going on? What's nice about years in which the 2520th day lands on Tisha B'Av is the 1335th day ends within a couple days after Tabernacles ends. The only 7 year period that works is 2015-22 because 2022 is just before 75 years from when Israel became a nation which constitutes a lifetime (Ps. 90.10).



This must be why nobody knows the day or the hour because the years the 2,520th day is not on Tisha B'Av, the 2550th day is on the Day of Atonement.

A key distinguishing mark is that there are 7 sets of 7 from June 7, 1967 to the Day of Atonement Sept. 23, 2015 so it makes one think the Tribulation would start in the year 2015.

7 x 7 x 360 = 17,640 days.
