Anyway my once-legit due date survey statistics now have a chart showing whether more babies are born under the full moon. I know it's an urban legend sort if idea, several studies have shown that unborn babies have no idea what the moon is doing and still come out whenever, but I had to do it because I was so proud of myself for making the algorithm to figure out moon phases! Anyway my graph also demonstrates the idea that babies do not disproportionately arrive during a full moon. I know you're shocked.
Did you know that the time between new moons is known to the tenth of a second? Is that cool or what? So if you know one new moon date, you know them all. I'm oddly impressed. We even know how to change the length of the cycles every few hundred years when the sun's gravity throws things off.
And yet... the best we can do for pregnant women is give them a due date that's "pretty good within a week or two". This, friends, is why I went into physics (well, engineering but you know) and not chemistry or biology.
Anyway back to the moon, this is what I made, you can go put in your birthday and tell me what you think:
