Military Time Converter Cheat Sheet: Zulu Time Made Simple (2026)
Military time looks intimidating until you learn the one rule behind it. Then it is genuinely easier than AM/PM, especially for shift work, flight ops, and anything involving people in different time zones. Here is the full chart, the rule, and the Zulu explanation you can actually use.
The full military time chart

|---|---|---|---|---|---|
| 12:00 AM | 0000 | zero hundred | 12:00 PM | 1200 | twelve hundred |

The one rule for converting in your head
- Hour is 1200 or less: read it as AM. 0900 = 9:00 AM. 0001 = 12:01 AM.
- Hour is 1300 or more: subtract 1200, add PM. 2145 − 1200 = 9:45 PM. 1700 − 1200 = 5:00 PM.
- Going the other way (PM only): add 1200. 3:30 PM + 1200 = 1530.
Minutes never change. Only the hour math matters, which is why the chart above is all most people ever need.
Zulu time: the timezone that ends arguments
Zulu time (spoken "Z") is the military name for Coordinated Universal Time (UTC). When a mission, a flight plan, or a maintenance window is set in Zulu, everyone on Earth is talking about the same instant:
- 1500Z in Iraq (UTC+3): 1800 local
- 1500Z in Germany (UTC+2 summer): 1700 local
- 1500Z on the US East Coast (UTC−4 summer): 1100 local
- 1500Z in Japan (UTC+9): 0000 local next day
The letter code for each zone runs down the alphabet (A through Z, skipping J), with Zulu being zero offset. This is why aviation and joint operations live in Zulu: a briefing at "0600Z" means exactly one moment worldwide, no "which base are you on?" confusion.

Who actually uses military time
Beyond the military: hospitals and nurses, pilots and dispatchers, emergency services, railroads, and anyone doing shift work across midnight. They all use it for the same reason: 1745 can only mean one thing, while 5:45 can mean two.
Common conversion mistakes
- Subtracting 1200 from 0900. Only hours 1300+ are PM. 0900 is morning.
- Writing 2430. Hours stop at 2359; a time like that is 0030 the next day.
- Dropping leading zeros. 0700 is "zero seven hundred," not "seven hundred" — the zero matters on radio and in logs.
- Forgetting the date rolls over in Zulu. 2300Z on Tuesday is already Wednesday in Japan. For multi-day ops, track the Zulu date.
Bottom line
Military time is one subtraction rule plus a chart. Learn the rule, keep the chart handy, and when you are coordinating across time zones, do everything in Zulu so nobody has to ask "your time or mine?"
Frequently asked questions
What is 1700 in military time?
1700 is 5:00 PM in standard time. For any military time of 1300 or higher, subtract 1200 to get the standard time. So 1700 minus 1200 equals 5:00 PM.
What is Zulu time?
Zulu time (Z) is the military and aviation name for Coordinated Universal Time (UTC). Operations that span time zones use Zulu so everyone means the same instant: 1500Z is 1500Z everywhere on Earth, then each local zone converts it.
How do you convert military time to standard time quickly?
If the hour is 12 or less, read it as AM (0001 is 12:01 AM). If the hour is 1300 or more, subtract 1200 and add PM. 0900 is 9:00 AM; 2145 is 9:45 PM.
Is midnight 0000 or 2400 in military time?
Both exist: 0000 starts the day and is pronounced zero hundred, while 2400 refers to the very end of a day, mostly in schedules and reports. In practice, midnight is written 0000.
How do you say military time out loud?
Read the digits: 0700 is zero seven hundred, 1545 is fifteen forty-five, and leading zeros are always spoken (zero five thirty for 0530). Nine is spoken as niner in radio usage.
