Once a month I go into my file server and run GZIP to compress files that are older than one month. I would like to know how to write a batch file that will compress by modify date or access time. Any help would be much appriciated.

We are using PKZIP from the command line.  Seems to work best when running batch files as you can pass paramaters to pkzip from the batch.  I would assume you could specify the greater than less then option within the batch file to get this done.  I would get PKZIP and go through the documentation.

This is the link to their site.  I must say that unzipping and zipping files in a batch file was the easiest when using pkzip as you can specify different commands right in the command.  I am not really sure how to specify the date range, but this should get you in the right direction.

You can create  a log file of the modified dates on a folder
Say you have a root folder by name Backup
then

c:\backup\dir > modifieddate.log

This would give a list of all the files and folders which have been modified.
You can use a for loop to check if the file or folder is older then a month and zip the file.

As per scripting. I would ask you to put a pointer in the programming.Who would be able to implement this idea.
