I didn't know there was a month 25.

that's not too hard really, you just extract the year month and date
components using substring-before and substring after and then calculate
the number of days in each case (ignoring leap years) then correct for
leap years by comparing y mod 4 - y mod 100 + y mod 400 in each case.
(or y-1 if the actual date is in jan or feb)

exctract the three fields as above, format using format-number() so they
are two or four digits exactly then concatenate the fields as yyyymmdd
and compare the result as integers.

XSLT2 has date arithmetic built in but only if you have your dates in a
standard format such as 2005-10-25 so even with xslt2 you'd have to use
substring (or regexp-replace) originally to get your dates in a standard
form.
