I divide into 1, 10, 100 and 1000 degrees only. 60, 12, 360, 24, 28 to 31 and 365 is for n00bs only.

@alfiestoppani Yep, that sounds right. I knew it was something really far back.

@Horathgar42 It's actually the Sumerians; but yes, they used the base number 60 which is very nice factor of 360.

Meghan is very good at drawing circles. <:3D~

Isn't 360 degrees because of sexagesimal, When the babylonians rounded a year to 360 days? I'm just guessing here, but it sounds right.
Small goof up on the animation at 3:54. As the Earth tilts, so does its shadow (its terminator). To really show the cause of seasons, it would have been better if the shadow had not tilted so that a solstice was being shown rather than an equinox.
