I'd like to add mt 2cents here and speak to alternate "day-count" concerning a "week-of-years"...
and specifically the last week ...the 70th week.



Sunday, June 12, 2011 is Pentecost this year.

Yom Kippur in 2017 is on Saturday, the 30th of September.
Note that in the Jewish calander, a holiday begins on the sunset of the previous day, so observing Jews will celebrate Yom Kippur on the sunset of Friday, the 29th of September.

There are 2300 days between those dates (not including the start date nor the end date)

I can't help but think that is significant in
some way.

That calculation does not occur in every "year-pair". It only happens occasionally.

The exact figure "2300" appears in the Bible [Daniel]
and is specifically referred to in the text as concerning the "end-times"

The exact figure "2520" does not appear in the Bible and is a surmised or assumed figure.

The 2300 count begins in 2011 & ends in 2017.

1.- 2011
2.- 2012
3.- 2013
4.- 2014
5.- 2015
6.- 2016
7.- 2017

A "week" of years or 7 different years.... the 70th week.

Daniel's 70 weeks are defined in terms as a count of "weeks-of-years" . One week is equal to the number 7. Reinterpreting that to some surmised calculation of "number-of-days" in a year is at best an assumption. We should note that each annual solar-return [ i.e.-"year"] is 365.25 days , approximately ,
resulting in a 7-year day-count of 2257 days ( approximately ).That count fits physical observable reality. A so-called "prophetic-year" of 360 days is an interpretive assumption only. [ 360 x 7 = 2520 ]. We note that Daniel defined the 70 weeks in terms of "weeks-of-years" and not in a "day-count" nor a count of moons [lunar month].
