Inauguration Day for US presidents is normally on Jan. 20th.  Add 1260 days to dusk Jan 20th and you will get dusk July 3rd.  A future July 4th will be the "Independence Day" from the beast.  I expect the next president to be the last.  (the red heifer will be 3 years old in Jan. 2017.  The next president will go into the temple Sept. 2017 at the star sign of Revelation 12, Rosh Hashanah 2017.

Friday, January 20th, 2017, the antichrist/ president will be inaugurated, but will not start his presidency until Monday, Jan 23, 2017 (imitating Hosea 6:2  After two days he will revive us; on the third day he will restore us, that we may live in his presence.)

Jan 23rd, 2017 add 1335 days to get to Rosh Hashanah Sept 19, 2020, which is a Sabbath New Moon (from Ezek 46:1 "'This is what the Sovereign LORD says: The gate of the inner court facing east is to be shut on the six working days, but on the Sabbath day and on the day of the New Moon it is to be opened.)  (Not every rosh occurs on the Sabbath obviously.)

Sept 28, 2015 (one of the "blood moons") would constitute an imitation "end of the world" and imitation "69 weeks until messiah" (Dan 9 70 weeks prophecy), 69 weeks ending on Jan. 23rd, 2017.
