Form a query for groups based on Expiration time attribute

Hi All,

I want to form a PowerShell query to fetch all the groups from FIM expiring on a particular date. Is it possible? I want to ignore the year and consider only month and date as this will be part of task scheduler and will be running on a monthly basis.

Currently the groups in FIM seem to have expiration time in the format mm/dd/yyyy 00:00:00 AM/PM.

I am guessing querying groups based on expiration time is not as simple as I thought. I have gone through the blog below as well but still I am not able to form the query for my requirement.

Any suggestions?
