Military Time Converter

How to use it

1. To convert to military time, type a 12-hour time such as 2:45 and set AM or PM. You can also type 2:45p.
2. To convert from military time, type four digits such as 1445 or 0730 on the right.
3. Each result shows the spoken form, so you know how to say it out loud.
4. Scroll down for the military time chart, and print it if you work shifts, in healthcare or in logistics.

Worked examples

• 2:45 PM → 1445. It’s after noon, so add 12 to the hour: 2 + 12 = 14. Write the hour and minutes together with no colon: 1445, said “fourteen forty-five”.
• 7:05 AM → 0705. Morning hours keep their number but always use two digits: 07. Said “zero seven zero five”.
• 12:30 AM → 0030. The midnight hour is 00 in military time, so 12:30 AM is 0030, said “zero zero thirty”.
• 12:00 PM → 1200. Noon stays 12, said “twelve hundred”.
• 2130 → 9:30 PM. The hour is over 12, so subtract 12: 21 − 12 = 9, and it’s PM.

How it’s calculated

12-hour to military:

• 12:xx AM (the midnight hour) → 00xx.
• 1:00 AM to 11:59 AM → same hour with a leading zero if needed (9:15 AM → 0915).
• 12:xx PM (the noon hour) → 12xx.
• 1:00 PM to 11:59 PM → add 12 to the hour (6:40 PM → 1840).

Military to 12-hour:

• 00xx → 12:xx AM. 01xx–11xx → same hour, AM. 12xx → 12:xx PM. 13xx–23xx → subtract 12, PM.

Military time is written as four digits without a colon and is often followed by the word “hours”. Civilian 24-hour time, used across the UK and Europe, is the same clock but usually written with a colon (14:45). Midnight can be written 0000 (start of the day) or 2400 (end of the day); this converter reads 2400 as midnight.
