Finding files less then 31 days old?

Hey, I'm trying to get a list of files 30 day sold or younger. I thought the following would to the trick: find . -type f -mtime 30 -ls But that only prints files that are exactly 30 days old. How do I do that "and younger" part? Less then 31 days would be a suitable substitute too.
