Military time is the 24-hour clock written without a colon and spoken in hundreds: 0000 is midnight, 1200 is noon, and each afternoon hour is the 12-hour value plus 12.
Reading military time in two moves
Hours 0-11 map straight to AM: 0745 is 7:45 AM (the leading zero is just padding). Hours 13-23 are PM: subtract 12, so 2200 is 10:00 PM. The only two memorized cases are 0000 (midnight, start of day) and 1200 (noon). Going the other way, add 12 to any PM hour except 12 PM itself, and write 12 AM as 00.
The spoken forms follow the digits: 0745 is 'zero seven forty-five', on-the-hour times use 'hundred' (2200 is 'twenty-two hundred hours'). Hospitals, aviation, and the military use it because no time ever needs an AM/PM tag that can be dropped or misheard.
How it’s calculated
Military to standard: hours 13-23 subtract 12 and take PM; 12 stays 12 PM; 1-11 are AM; 0 (or 24) is 12 AM. Standard to military: PM hours except 12 add 12; 12 AM becomes 00; minutes are unchanged in both directions. Inputs are parsed from digits, with a/p detected for 12-hour input; 3-digit entries read as H:MM, 1-2 digits as whole hours.
Times are wall-clock conversions only — no time zones, and seconds are not carried.

Common mistakes
- Adding 12 to morning hours: 0900 is 9:00 AM, not 9:00 PM — only 13:00 and later are afternoon.
- Converting 12:30 AM to 1230 — it's 0030; the 12 AM hour is written as 00.
- Reading 2200 as 22 minutes past something; without a colon the first two digits are always the hour.
- Writing 12:00 PM as 2400 — noon is 1200; 2400 is occasionally used for end-of-day midnight, but 0000 is the standard.
Frequently asked questions
What is 22 in military time?
2200 hours — 10:00 PM. The rule for any military hour of 13 or more is to subtract 12 and call it PM: 22 − 12 = 10.
What's the conversion formula?
Military to standard: hour − 12 with PM if the hour is 13-23; hour 12 is noon; 1-11 are AM; 00 is 12 AM. Standard to military: add 12 to PM hours except 12 PM, and write 12 AM as 00. Minutes never change.
Is midnight 0000 or 2400?
0000 is the standard, marking the start of the new day. Some schedules write 2400 to mean end-of-day midnight of the previous day; this converter accepts 2400 and normalizes it to 0000.
How do you say military times out loud?
Read the digits in pairs: 0745 is 'zero seven forty-five'; whole hours use 'hundred', so 1800 is 'eighteen hundred hours'. The word 'hours' is customary but optional.
Is military time the same as the 24-hour clock?
Functionally yes. The 24-hour clock writes 22:00 with a colon; military style drops the colon (2200) and adds the spoken 'hundred hours' conventions.
