Idea: June 3 (6/3) should be "Rule 63 Day"

Seriously, how has nobody thought of this one before? We've got Pi Day, May the Fourth, and all these other made-up holidays where people post art on a specific theme, as well as month-long events like Mermay and Dogust and Sneptember... Why not a day for gender-swap art? Everybody knows someone (or several someones) who would dig this idea for one reason or another, so you've got a little over a month to get the word out.

Would overseas folks also do it on the 6th of March?
Lessee, last one was June 12th, 2024 (6/12/24), so the next one is July 14th, 2028 (7/14/28).
