Delete files older than a certain date

[jrhutch]

As part of our install process, we have a utility that backs up our database info, and some report files. When installing our new product, we only need to keep report files that are less than a year old, and removing the older files speeds up our install significantly.

Is there a way to delete files out of a directory based on a wildcard search, and could they be searched quickly using their creation dates?
