-atime n File was accessed n days ago
-mtime n File was modified n days ago
-size n File is n blocks big (a block is 512 bytes)

-size +100 Matches files larger than 100 blocks (50KB)

Changing the output information
If you want more than just the names of the files displayed, find's -printf action lets you have just about any type of information displayed. Looking at the man page there is a startling array of options.

These are used the most:
%p filename, including name(s) of directory the file is in
%m permissions of file, displayed in octal.
%f displays the filename, no directory names are included
%g name of the group the file belongs to.
%h display name of directory file is in, filename isn't included.
%u username of the owner of the file
