Dormition / Assumption Fast (August 1-14, Eastern Catholic / Orthodox)
https://infogalactic.com/info/Dormition_of_the_Mother_of_God
The Feast of the Dormition is preceded by a two-week fast, referred to as the Dormition Fast. From August 1 to August 14 (inclusive) Orthodox and Eastern Catholics fast from red meat, poultry, meat products, dairy products (eggs and milk products), fish, oil, and wine. The Dormition Fast is a stricter fast than either the Nativity Fast (Advent) or the Apostles' Fast, with only wine and oil (but no fish) allowed on weekends.
If you follow what is happening within the Catholic Church, in regards to the Traditional Latin Mass, you will understand a bit what is happening. The TLM does not do a two-week fast, but they celebrate the Assumption. When the Mass was devastated by the changes of Vatican II, the calendar and requirements changed in a lot of negative ways.
oh yes I'm very much aware of what happened
I believe it implies sedevacantism today or there's no pope or churches to go to that we know of
