uncustomary
Outside the norm
Uncustomary means not in accordance with custom or usual practice—the opposite of customary.
Something uncustomary departs from what is typical or expected: It was uncustomary for him to arrive late.
The word is somewhat formal; *unusual* or *not typical* often serves the same purpose in everyday speech.
