Gerry,
	You had mentioned the term prophetic year, in discussing the prophecy given to Daniel.
That the prophetic year is 360 days, rather than the actual 365.2422 days
			(i.e. with an extra February 29 every 4 years, but not on years ending in "00", unless it's divisible by 400)
			(I think that in Israel they had their own way leaping, using a second month of Adar)
In the period of 490 years, if they were to be only considered to be prophetic years of 360 days, that would a big difference.
The 490 prophetic years would 2,568 & ⅔ days less than 490 actual years.
Also, each prophetic year would therefore have Passover falling 5 days shorter.
So that after 36 prophetic years, Passover, with the prophetic years, would end up in the fall, instead of in the spring.
And, then after 72 years, an entire Passover would have been lost.
With that in mind, then how does the year of Jubilee fit in?
Was the Jubilee to be according to the prophetic year?
