When Does the Tribulation Start? When Does Jesus Stand on the Mount of Olives?

I don't understand how the first rapture can occur on any other day than Sept. 14, 2015 (Tishri 1), the Feast of Trumpets. And I don't understand how Jesus can return on any other day than Av 7, Aug. 10, 2022. Calculate it yourself.

These two dates are exactly 2,520 days apart (7 x 360),

Sept. 23, 2015 is the Day of Atonement, the holiest day of the year for Jews and which ushers in the 50th year, the year of Jubilee.

The Lord then spoke to Moses at Mount Sinai, saying, "Speak to the sons of Israel, and say to them, 'When you come into the land which I shall give you, then the land shall have a sabbath to the Lord. Six years you shall sow your field, and six years you shall prune your vineyard and gather in its crop, but during the seventh year the land shall have a sabbath rest, a sabbath to the Lord…You are also to count off seven sabbaths of years for yourself, seven times seven years, so that you have the time of the seven sabbaths of years, namely, forty-nine years. You shall then sound a ram's horn abroad on the tenth day of the seventh month; on the day of atonement you shall sound a horn all through your land. You shall thus consecrate the fiftieth year and proclaim a release through the land to all its inhabitants. It shall be a jubilee for you (Leviticus 25:1-4, 8-10, NASB).

The Day of Atonement is the 10th day of the new civil year,

On June 7, 1967, Israeli troops moved into the Old City and stood at the Western Wall (Wailing Wall) for prayer. Rabbi Shlomo Goren declared:

"We have taken the city of God. We are entering the Messianic era for the Jewish people, and I promise to the Christian world that what we are responsible for we will take care of."

From Sept. 7, 1967 when Israel walked into Jerusalem and took it over to Sept. 23, 2015 is exactly 17,640 days or 49 x 360 days per year. See for yourself,

Call me crazy, I don't care. I know I am right with this timing because of the Tetrad in 1949/50, 1967/68 and 2014/15.

So the first rapture "before the throne (Rev. 7.9) occurs on Sept. 14 or 15, 2015. The last trumpet rapture and resurrection occurs exactly 1801 days after the day of the first rapture (42 x 30) + (5 x 30) + (13 x 30 + 1) which is on August 18, 2020.

The 42 is the first 42 months in the Tribulation comprised of four trumpets. The 1st woe or 5th trumpet is said to be 5 months. And the 2nd woe is said to be one year, one month and a day. That leaves 24 thirty day months from the last trumpet resurrection to when Jesus steps down on the mount of olives on the 2,520th day of 84 thirty day months.

Call me crazy, but that's what the Bible says, and I believe God's word is inerrant.

I find it hard to believe the Temple will beging construction in 2010 and be completed by 2016 like it would need to be with 2300 days left to the Tribulation, but I am watching.
