Louisoix wasn't created until the 19th June , so that's only 82 days including today (Friday). That means there's at least 8 more days until the 90 day deadline before anyone can transfer off, and that's only if you created on the first day it was available.

But if this is your first character though, check your email. At the point you register a service account Square Enix email you confirmation (Subject: [Square Enix Account] Service Account Registration Notification). Perhaps that will give you a more exact day. Of course if it's not your first character that doesn't help, same as if you registered an account and for some reason didn't create a character straight away.
