I ran across this page (http://www.direct.ca/trinity/360vs365.html) while looking up something about calenders and thought I would see what you guys thought. (I'm not promoting the idea he describes.)

The page calculates that if the earth orbited the sun fast enough that there were 360 24hr days in a year that the moon would also rotate faster so that a month would be 30 days making everything fit into 12 even months. He then claims that this was the type of reckoning used in the Bible and other ancient calender systems and uses that as evidence that the earth really had a 360 day year.

The difference in speed between 365.2422 days per year and 360 days per year is equal to 20.9688 minutes per day. This is not a difference in our 24-hour time period but it would take the earth 20.9688 minutes less time per day to travel that same distance in the orbit around the sun.

365.2422 days -20.9688 minutes per day = 360 days

If you had a year = 360 days per year and slowed the orbit of the earth around the sun by 0.433792 km/s (The difference between 30.22379 km/s and 29.79 km/s), you would end up with a year that takes 365.2422 days. This slower speed would cause 5.2422 days extra per year to make one complete revolution around the sun

There is no time dilation or anything extraordinary here. We have only slowed the speed of the earth down. We have not changed spin of the earth in a 24-hour period and we have not changed the speed of the moon around the earth.

However, if the earth had a year of 360 days per year (= earth's orbital speed of 30.22379 km/s) the moon would now automatically have a 30 day lunar month without changing the speed of the orbit of the moon!

So why did early civilizations around the world use calendars with months of 30 days and years of 360 days? These calendars seemed to function well until sometime in the 8th century BC when suddenly it became necessary to change them. Most civilizations around the world began to modify their calendars to allow for 5 extra days for the year and 6 fewer days for a lunar year. A lunar year is 12 full months; a modern lunar year is 354 days (12 months x 29.5 days).

Now, I'm not interested in the religious aspect of this. However I was wondering if (1) his calculations would be correct assuming that the earth and moon had a faster orbit, and (2) what possible non-supernatural mechanism could conceivably cause a rapid shift (astronomically speaking) in orbital velocity/period consistent with this guys theory?
