Military Time Converter

The 24-hour clock numbers the hours from 00 to 23, so there is no am or pm. It is used for timetables, flights, hospitals, the military and most of the world’s digital clocks. Type a time in 24-hour form, such as 1430 or 14:30, or in 12-hour form, such as 2:30 pm, and see it in both.

How to use the Military Time Converter

1. Type a time, for example 1430, 14:30, 14h30 or 2:30 pm.
2. Read the 24-hour time, the military form and the 12-hour time.
3. For midnight, type 0000 or 12 am; for midday, type 1200 or 12 pm.
4. Use the table below for quick conversions.

Converting 1430 and 9:45 pm

1430 is 2:30 pm: subtract 12 from any hour from 13 to 23 and add pm. In military style it is said “fourteen thirty hours”. Going the other way, 9:45 pm is 21:45: add 12 to any pm hour from 1 to 11. Midnight is 00:00 (12:00 am) and midday is 12:00 (12:00 pm).

How the 24-hour clock works

Hours 00 to 11 are the morning, and the 12-hour time is the same except for 00, which is 12 am. Hour 12 is noon, 12 pm. From 13 to 23, subtract 12 and add pm. Military time is usually written without a colon (1430) and spoken as hours, while many countries write 14:30 or, in South Africa, often 14h30. Some timetables use 24:00 for the very end of a day, which is the same moment as 00:00 the next day.

Common mistakes

• Calling midday 12 am. Midday is 12:00 pm; midnight is 12:00 am.
• Subtracting 12 from morning hours. Only hours 13 to 23 change; 09:00 is simply 9:00 am.
• Adding 12 to 12 pm. 12:30 pm stays 12:30 in 24-hour time.
