Well I guess we don't all know it otherwise we wouldn't be asking the questions and getting wrong answers. If it's not a scheduled day off then there's no additional pay after 0200 (or vacation day after 1600 for that matter) but it also doesn't count as one of the 12 scheduled days off. "Day Off" is defined in the CBA as a calendar free from all duty with the company which occurs in a pilot's domicile.
