Daniel 12:11-12 tells us the abomination takes place on day 1290...from what? I believe it's from the start of the 70th week. When is that? The next feast in line: Yom Teruah: it's a perfect fit. Joel 2 even clues us in to this:
if you don't know what Yom Teruah is:
Lev 23:24 Speak unto the children of Israel, saying, In the seventh month, in the first day of the month, shall ye have a sabbath, a memorial of blowing of trumpets, an holy convocation.
A convocation is:
H4744
מקרא
miqrâ'
mik-raw'
From H7121; something called out, that is, a public meeting (the act, the persons, or the palce); also a rehearsal: - assembly, calling, convocation, reading.
Lev 23:25 Ye shall do no servile work therein: but ye shall offer an offering made by fire unto the LORD.
Joe 2:1 Blow ye the trumpet in Zion, and sound an alarm in my holy mountain: let all the inhabitants of the land tremble: for the day of the LORD cometh, for it is nigh at hand;
-skip-
Joe 2:11 And the LORD shall utter his voice before his army: for his camp is very great: for he is strong that executeth his word: for the day of the LORD is great and very terrible; and who can abide it?
Joe 2:12 Therefore also now, saith the LORD, turn ye even to me with all your heart, and with fasting, and with weeping, and with mourning:
Joe 2:13 And rend your heart, and not your garments, and turn unto the LORD your God: for he is gracious and merciful, slow to anger, and of great kindness, and repenteth him of the evil.
Joe 2:14 Who knoweth if he will return and repent, and leave a blessing behind him; even a meat offering and a drink offering unto the LORD your God?
Joe 2:15 Blow the trumpet in Zion, sanctify a fast, call a solemn assembly: ( a holy convocation)
Joe 2:16 Gather the people, sanctify the congregation, assemble the elders, gather the children, and those that suck the breasts: let the bridegroom go forth of his chamber, and the bride out of her closet.
Joe 2:17 Let the priests, the ministers of the LORD, weep between the porch and the altar, and let them say, Spare thy people, O LORD, and give not thine heritage to reproach, that the heathen should rule over them: wherefore should they say among the people, Where is their God?
So if the 70th week started on Yom Teruah 2009, day 1290, the abomination that causes desolation is April 1, 2013, the 7th day of Passover:
