This is an awesome site! I told a retired county board member (he’s in his 70s) that I could tell him what the phase of the moon was on the day he was born, and he gave me this look of disbelief. Maybe I should have placed a bet on this! I plulgged in his D.O.B. and he was surprised. I’ve also shared this site with family and friends.
I definitely plan to use it when I’m teaching. It might even be a good resource for a math or geography webquest.
