Although the Church of Satan was founded 4/30/66, 6/6/66 is also meaningful to them. They celebrated their 50th anniversary 6-6-18.
The is a lot of speculation was to what will happen when - but 6-6-18 remains a special day to them, as does 6-21-18 / 6-22-18….. and we are still in full moon today and tomorrow…. that makes witches crazy - witch being a genderless term… how appropriate for them
