Let's say that the files you are looking for were created 60 days ago,
you could use the following:

find . -type f -mtime 60 | xargs fgrep -l 'string'

Note! It seems that what -mtime finds depends on the system or the
version of find.
On HP-UX 11i I found that this found all files created 60 days ago, but
only files created from 00:00 until the current time today.
On Solaris 2.6 I found that this found all files created in the 24 hours
which were 60 days ago.

What you can do is that you do an "ls -l", and find you self two
reference files. One created _before_ the files you want to search, and
one created _after_ the files you want to search.

You then do:
find . -type f -newer file1 -a ! -newer file2 | xargs fgrep -l "string"

man find
man grep
