Return 1 or 0 based on Date Range

[kwjoh]

I need a function that will give a 1 if a range covers a month and a 0 if it does not. The entire month does not need to be covered by the range, just a single day, to return a 1.

Here is what I have (short version) the full list goes through 2014:

start 5/23/07
end 9/20/07

The result should be this:
2007
January 0
February 0
March 0
April 0
May 1
June 1
July 1
August 1
September 1
October 0
November 0
December 0
