One business day is required in the Payment Service Directive. You still occasionally see two days from German banks, only few of them actually can manage a zero day transfer. I operate a Dutch bank account solely for the purpose of making fast transfers to German accounts which works really well. Once I tested that I was able to do a zero day transfer from a German bank to the Netherlands and then to another German bank. The same without the Dutch intermediary was a day slower.
