12am

Clock strikes twelve

12am is midnight—the first moment of a new calendar day.

The designation causes confusion because it marks the transition between days rather than falling clearly within one.

To avoid ambiguity, many prefer "midnight" or "12:00 midnight." Technically, 12am begins the day while 12pm is noon.

The show starts at 12am, so we'll be up late.
