There is a break in Daniels prophetic weeks, at 69.5. For background, I refer to this and related posts. The bottom line is that we are now in 3.5 years of transition, and the 70 weeks of seven years of Sefer Daniel are finished at Tisha B'Av 5775. This is the prophetic end of Bayit Sheni. After that there is another week of seven years to prophetically finish Bayit Rishon. After that, there are two more weeks, of seven years, to the end. This is the principle of Mo'ed, Moadim, and a half, as explained.
So, at Tisha B'Av 5775, the time given to the Cohanim will be over. At the end of "Bayit Rishon," at Tisha B'Av 5782, the time will be, let us say, more than over.
