(apologies for top-post)
As tempted as I am, I think newsyslog(8) may be what you want.
Missing information in your post is how you intend to timestamp the files -- by filename? by content? If by-content, then is it a good assumption that the data is one entry per-line? ... and if-so, is the timestamp in that line? These are all questions that would be needed to script what you're asking for (not that I'm volunteering or anything like that).

Subject: Fun Scripting Problem
I know how to do this in Python, but I really want to do it in
straight Bourne shell. I have some ideas, but I thought I'd
give you folks a crack at this Big Fun:
a) You have a directory of files - say they're logs - generated
at nondeterministic intervals. You may get more than one a day,
more than one a month, none, or hundreds.
b) To conserve space, you want to keep the last file generated
in any given month (the archive goes back for an unspecified
number of years), and delete all the files generated prior to
that last file in that same month.
c) Bonus points if the problem is solved generally for either files
or directories generated as described above.
These are not actually logs, and no, I don't think logrotate can
do this ... or can it?
