Military Time Military (or European) time is based on 24 hours in a day. U.S. standard time is based on 2 times 12 hours in a day:    • mornings – A.M. (ante-meridian)   and    • afternoons – P.M. (post-meridian) Just add 12 hours to Standard time, and you'll have the Military time. STANDARD MILITARY
