Military time converter switches between 12-hour civilian clocks and 24-hour format.
About this calculator
Military time converter switches between 12-hour civilian clocks and 24-hour format. Enter 2:30 PM and get 14:30. Enter 09:15 in 24-hour mode and get 9:15 AM. Useful when reading Indian Railways timetables, hospital shift rosters, or flight departure boards.
India officially uses IST (UTC+5:30) on both formats. Confusion happens around midnight — 12:00 AM is 00:00, not 12:00. 12:00 PM is noon (12:00), not midnight.
Pair with [[time-zone]] for international meetings, [[time-card]] for shift hours, and [[countdown]] for event timing. For date arithmetic use [[date-difference]].
