Reference - The Moon

This is wild stuff! I am really impressed how the Mayans mastered the complicated task to get a grip on mooncycles with pure integer mathematics: They averaged the lunar cycle with 29 days and counted how many newmoons passed until the date and moon phase matched again. Guess what number showed up!?! But I don't want to spill the fun of actually simulating this voyage... Click start and watch!
