If the dates are in column A, the count is =countif(a:a,"=" &
date(2005,12,1))-countif(a:a,"=" & date(2006,1,1)).
In words, count the number of entries dated Dec 05 or later, then subtract
the number dated Jan 06 or later. The net is those dated Dec 05.

entries I have in a monthly time period. i.e. how many insances do I have in
December 05?
