Let’s talk about the Vernal Equinox for a moment here, shall we? It falls in a very weird way this year. It’s a specific moment in time, and that moment happens to fall at 10:00 PM my local time (Arizona, USA) on March 19th. But that means it happens at 4:00 AM UTC/GMT on March 20th.
I couldn’t figure out which date to put all the equinox-specific holidays on, so I left them out. And boy, are there a bunch: World Storytelling Day! International Astrology Day! International Earth Day! International Day of Nowruz! And Snowman Burning Day, which is so totally weird that I’m putting an asterisk on it for next year’s list, so I can hopefully use it when we all agree about what day the equinox falls on.
