Military time (24-hour) is widely used in military, aviation, healthcare and computing to avoid AM/PM confusion.
What is military time?
Military time is a 24-hour time format. Midnight is 0000 or 0000 hours, and 1 PM is 1300 hours. It is often written without a colon (e.g. 1300 instead of 13:00).
How to quickly convert?
12-hour to 24-hour: add 12 for PM hours (except noon). AM hours stay the same, midnight = 00. 24-hour to 12-hour: subtract 12 for hours > 12 = PM, 12 = noon PM, 0 = midnight AM.
