CORRECTION!
Above, I stated that
2520 / 12 = 1260 / 24 = 210
And that is not correct.
2520 / 12 = 1260 / 6 = 210
There. Fixed it. And even if nobody else is as excited about a bunch of math on an Internet forum about religion, I'm still pretty stoked that I just took out a calculator and showed that those funny Bible numbers all the religious quacks talk about are entirely astrological.
EDIT:
One last thing, I can't resist! Hahaha
2520 * 10 + 720 = 25920 (the length of a Great Solar or Platonic Year)
