Birthday-shift 

Verb- The practice of celebrating one’s birthday on a different day because that person’s actual birthday is not convenient for the party thrower(s).

John: Dude… Jane is going to be so pissed off when we celebrate her birthday on Friday instead of her real birthday date on Wednesday. Missy isn’t going to be here on Wednesday so she forced us to pull a Birthday-shift.
