What about the two witnesses? Is this the beginning of the 7 years or in the middle of the 7 years? Will the whole world know they are in action because they withhold rain for 3 1/2 years? Between the floods and droughts and fires and weather phenomenal activity, volcano, earthquake, tsunami, tornadoes, astroids falling from the heavens, large hail coming down, etc. and the two witnesses withholding rain, that would be a period of tribulation.
Rev_11:3 And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth.
I study the calendar with a view of starting events. 2020 was the middle of the final jubilee cycle. W.H.O. ordered a lockdown on the whole world. One could view that event on March 11, 2020 as a starting point for tribulation. However, there is another event that hit over 60 countries and that was triggered by the George Floyd murder and riots of 2020. This occured on May 25, 2020. In Daniel we find three verses with a counting of days.
Dan_8:14 And he said unto me, Unto two thousand and three hundred days; then shall the sanctuary be cleansed.
Dan_12:11 And from the time that the daily sacrifice shall be taken away, and the abomination that maketh desolate set up, there shall be a thousand two hundred and ninety days.
Dan_12:12 Blessed is he that waiteth, and cometh to the thousand three hundred and five and thirty days.
Starting with the 2300 days and start with May 25, 2020 brings you to September 11, 2026. At this point the two witnesses begin prophesying for 3 1/2 years. They are killed on 1256th day and lay dead for 3 1/2 days before standing alive and being called up. That date falls on February 18, 2030 thru February 21, 2030. February 18, 2030 is Shushan Purim and the tradition is to give gifts.
Rev_11:10 And they that dwell upon the earth shall rejoice over them, and make merry, and shall send gifts one to another; because these two prophets tormented them that dwelt on the earth.
From that day of being called up hither, count to 1335 days. February 20, 2030 Plus 1335 days = October 16, 2033/Tishri 23. Tishri 22 is the Last Great Eighth Day which is at the end of Feast of Tabernacles on Tishri 21.
Dan_12:12 Blessed is he that waiteth, and cometh to the thousand three hundred and five and thirty days.
Mat 24:21 For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.
Mat 24:22 And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.
This is one theory that the end of the great tribulation will end on October 16, 2033. This is 11 years before the end of this final jubilee cycle we are now in.
So which of these dates here in the last days are we not to know the day and hour? That is a Hebrew idiom for the 1st day of the 7th month/Feast of Trumpets.
