July 4th, 2076? Yup, that's a Saturday.

When I was younger, I used to think that it would be really cool to be able to figure out (in my head) the day of the week for any date. I don't remember ever really thinking that this would be useful, in particular, but that it would be more of a nifty parlor trick. A "Have fun at parties! Impress your friends!" kind of thing. Then, I forgot about it.

Fast forward a few decades, and like magic, the Internet holds the answers. Whee! Time and Date has one good approach. There's a different method over on the Grey Matters blog.

Part of me still thinks that this would be really fun to learn, and part of me thinks it's sort of like knowing how the sausage is made. What do you think - worth the time or waste of time?
