In my case more than 1 week
I heard my EAD approved on Oct 24th. I still didn\'t get it yet. These days, anthrax is a headache for mailing system. I am waiting patiently. If you couldn\'t get it when you need it then go to your local ASC to get a temperary card, I heard you can do that if your EAD has been approved or your application pass 90 days.
