I'm glad to see people are easily debunking the "14000 Day Generation" idea floating around.   However I wanted to respond to this comment:

There is Bible evidence that months were once 30 days, but THERE IS NO EVIDENCE that years ever were 360 days.

Actually, the Bible only talks about 12 months in a year as well as strictly 30 day months (flood account) which multiplied of course gives you a 360 day year.

1Ki 4:7 -  And Solomon had twelve officers over all Israel, which provided victuals for the king and his household: each man his month in a year made provision.

1Ch 27:1 The twelve captains, one for each month

Rev 22:2 In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: 

This agrees with ancient history.  We used to have a 360 day year as all ancient calendars before 7th century BCE record.  These calendars were changed when the Earth's orbit was slowed down to 365¼ days and the lunar cycle shortened as well to 29½ days apparently after a close flyby with Mars.  Intercalation had to be added since the month no longer divided evenly into the year.  Thankfully nobody tried to change the number of degrees in a circle from the original 360 to match the later day-divisions of earth's revolution around the sun.

However no need!   Revelation tells us that this literal 360 / 30 calendar is returning after we make another close flyby, this time with Wormwood / Planet X (in front of us, causing us to speed up and the year to shorten, and the month to lengthen as a result of the greater angular distance the moon as to travel to reach conjunction).

See my article for more details and links to sites explaining the above and how it all works out.
