Please see here for context. There are 33 "days" after birth before a "woman" can go to the Beit HaMikdash / the place of the Beit HaMikdash if the child is a boy. It is a 66 day wait if the child is female.
According to the shitah that I have brought before, the 66th Yovel year that Am Yisrael will have ever been through, starting from the time of Yehoshua bin-Nun, is 5776.
The details of the list:
2555 is Yovel year 1. Continue every 50 years, last Yovel being 3305. For the next two Yovels, count forward 49 years. We have counted up to 18.
3465 is Yovel year 19. Continue every 50 years, last being 3865. For the remaining Yovels up until 5776, count every 49 years.
