I hope you will prayerfully consider the following.

For the Jews (and indeed all the world!) the 9th of Av is primarily a day connected with rebellion and the destruction of the Temple(s).  (NOTE: often neglected in the discussion of the Temple is that it was not a "Jewish" Temple or a Temple just for Jews, but was by God's sovereign intent "a house of prayer for all nations." [Isaiah 56:7, Mark 11:17]  It was OUR Temple, also.)  The 9th of Av is known as "the fast of the fifth month and, as such, is referred to in Zechariah 8:19 where the Lord promises that this particular day will be "joy and gladness and cheerful feasts" at some future time.  That is, some extremely joyful event will occur on some future 9th of Av that will completely overwhelm the misery usually associated with this particular day.  As I will suggest, the anointing of the Millennial Temple could be that event.

Daniel 9:24 lists six (seven in the LXX) "agenda items" that the Lord will accomplish for the Jews and Jerusalem before the 70 weeks are concluded.  The final item is "anoint the Most Holy."  There are a few ideas on what this might mean, but I think it's clarified in Ezekiel 43:12, 44:13, 45:3 and 48:12.  The "Most Holy" or "Most Holy Place" is the Millennial Temple complex.  Something or someone is "anointed" when it is put into service.  Kings were anointed to begin their reigns.  Accordingly, it makes sense that the Millennial Temple will be anointed when it is "opened" at the beginning of the Millennium.

Jesus is not the "most holy" in this context.  He is ALREADY King of kings and Lord of lords.  He was anointed for burial.  He is already serving as our High Priest.  So He can't be anointed at some future time to inaugurate His role as Savior, High Priest, or King.  As for an anointing to a prophetic office, we refer back to Daniel 9 where we see that vision and prophecy are "sealed up" (presumably fulfilled and concluded) by the end of the final 'week' so Jesus would have no role as a Prophet.

It would fulfill part of the Zechariah 8 prophecy for the Millennial Temple complex to be anointed on the 9th of Av in some future year.  According to HebCal, the 9th of Av seven years from now will be August 1, 2028.  If that is the end of Daniel's 70th week, we can count back 2,550 days to calculate the beginning of the 70th week. If we assume that the Temple is anointed on the very last day of Daniel's 70th week, the final seven years would begin on this coming August 8th.   

The final seven years begins with the confirmation of a covenant.   The rapture must happen before the covenant is confirmed.  Day #1 is when the covenant is confirmed.   There are lots of folks who think the covenant is a 7-year "peace treaty" between "The Antichrist" and the Jews/Israel.   I find this conjecture to be extremely problematic, and I've concluded that Daniel 9:27 is talking about a covenant confirmed by Jesus the Messiah with the Jews.

Twice in Revelation, Jesus warned us concerning "those who say they are Jews and are not, but lie."  We see something similar in politics, with those who say they are conservatives and are not.  They run as conservatives, make conservative promises, get conservative support, but then when they are in a position to act, they betray those who trusted them.  I think the same thing is going on in the land of Israel.  Tel Aviv is the gay playground of the Mediterranean, claiming to be the "gayest city on the planet."  Abortion is a government-sponsored "right" and the State of Israel has killed more Jews than Hitler ever did.  Or perhaps "Jews" - as they may have neither legal nor genetic claim as Jacob's descendents.  https://www.unz.com/pgiraldi/joe-biden-bows-to-force-majeure/  I bring this up because we expect, from prophecy, that the Jews will be preserved in the wilderness for 1,260 days (Rev. 12:6,14).  We can probably expect that the "Jews" who are running the State of Israel will remain in place.   True Jews and those resurrected will be gathered and preserved, possibly in Petra.  King David will be king over them (Ezek. 37:24).   It appears that at the Parousia, David will be relegated to "prince" and will be their prince forever (verse 25).  For more on David's role and status in the Millennium, see Ezekiel 44:3, 46:2-18.

God made certain earthly promises to faithful Jews (read Hebrews 11) who died before receiving them.  God will raise them up and they will receive everything God promised.  This, I believe, will be the confirmation of the covenant.  Ezekiel 37 is a resurrection passage, and Revelation 7:3-8 is the confirmation (ref. Ezek. 37:26).  The final seven years begins with an earthquake, a resurrection event, and a confirmation.  (The "shaking" in Ezek.37:7 [H7493] is properly rendered "earthquake.")  I am rather persuaded that the resurrection of the Jews in Ezek. 37 happens at the same time as the resurrection/rapture of Christians.  This could be several days before the final 'week' begins.

If this conjecture is correct (or reasonably close), then Satan's 42-month global reign of terror (Rev. 13:5) must end by March 28, 2025.  This means it begins no later than this coming October 15.

So a rapture on the upcoming 9th of Av is a distinct possibility, but any day this month will work.
