I can't remember the formula now but I used to do it too. You need to remember about 12 numbers and then follow some obvious rules. It got it down to about a second. The only problem was, everyone asking me the dates didn't know what day they fell on so didn't know if I was right or not.
Perhaps you don't use the formula, though. That would be better.
Is it normal that I am a calendar savant?
