What is the 12h / 24h / Military Time Converter?
Train timetables, flight tickets and many offices use the 24-hour clock, while daily speech in Pakistan uses AM and PM. The army, hospitals and aviation use military time, written without a colon (such as 1730 hours). This converter switches between all three.
To add or subtract hours from a time use the Time Calculator; to convert between cities use the Time Zone Converter.
