April 19 is the calander date.
The holiday is generally on the 3rd Monday in April.

I am not disagreeing with you. Just presenting additional information.
The anniversary of Oklahoma City. Columbine. Hitler’s Birthday. The day my buddy freaked out on mescaline in high school.
FWIW:
As I’ve posted on other threads, April 19 also happens to be a significant blood sacrifice day for the worshippers of the unholy one(s)
I want the positive connotations of this date to outweigh the negative ones this year!
