AD Users Disabled Date

I have around 200 disconnected AD users from their mailboxes.  I want to delete these mailbox disconnected AD user Accounts which are older than one year.  I checked the Object tab of these disabled/disconnected users in AD and they all show different dates. 

Is there a way/script that I can use to export out list of these disabled/disconnected AD users which are disabled for more than a year? 

Thanks!
