Report on AD accounts that have been disabled for 45 days. (4225569)

There are no attributes in AD for the User objects that store when the object was disabled, just disabled or enabled. 

As such, determining when an account was disabled is not generally possible. 

You can however return objects that are disabled and that have not logged on in x days.

This does not tell you when the account was disabled but can provide an idea about how long the account has been inactive.
