What is Military Time and Why is it Used?
Military time is a precise, four-digit number timekeeping system based on a 24-hour clock running continuously from midnight (0000) to 2359. Unlike standard 12-hour civilian time, military time eliminates the need for “AM” (Ante Meridiem) and “PM” (Post Meridiem) markers. This drastically reduces ambiguity and prevents critical scheduling errors in mission-critical timing environments utilized by the armed forces, military personnel, pilots in aviation, nurses in the healthcare field, and emergency responders like police and EMTs.
While similar to regular time used in Europe, true military notation omits the colon (e.g., 1400 instead of 14:00) and mandates a leading zero for morning hours. In software, navigation, and logistics, this format mirrors global standards like ISO 8601, Coordinated Universal Time (UTC), Greenwich Mean Time (GMT), and Zulu Time—making accurate conversion essential for seamless global communication.
How to Convert Military Time (The Mechanics)
Follow these core mathematical rules (add 12 or subtract 12) to easily translate between civilian time and a 24-hour format:
- Morning Hours (0000 to 1159): For hours from midnight to 11:59 AM, the numerical value remains identical. Always use a leading zero for single-digit hours (e.g., 0800). Simply insert a colon between the hours and minutes and append “AM” (e.g., 0900 becomes 9:00 AM).
- Noon (1200): The four-digit number 1200 represents exactly 12:00 PM (Noon) in standard time. No conversion math is required.
- Afternoon & Evening Hours (1300 to 2359): For any military value of 1300 or greater, simply subtract 12 from the first two digits, insert a colon, and append “PM”. For example, to convert 1730: subtract 12 from 17 to get 5, resulting in 5:30 PM civilian time.
- Midnight (0000 or 2400): Midnight is unique. It can be written as either 0000 (the start of a new day) or 2400 (the end of a day). Both represent 12:00 AM standard time.

Frequently Asked Questions
What is 1700 in military time?
1700 in military time is exactly 5:00 PM in standard 12-hour clock format. To calculate this, simply subtract 12 from the hour (17 - 12) to get 5, and append PM.
