Show HN: Sumday – a daily game: make an equation from today's date

Hi all! This is a game I made where you try to make an equation from today's date, using every digit in order. I had a substitute math teacher in middle school who did this on the whiteboard one day, and I've been doing it for fun every so often since.

I was inspired by wordle to make it into a daily web game, but unlike wordle and other games in that genre, you don't need to guess one specific solution. Any valid equation works. I found that mechanic more enjoyable and let me focus on just the math. Each day does have a "canonical" solution that you can gradually reveal with the Hint button, but that doesn't need to be your equation.

Let me know what you think, I hope you enjoy it!
