A fast, local military time converter
This military time converter instantly translates any time you enter into three distinct formats: standard 12-hour time with AM/PM, standard 24-hour time with a colon, and military time without a colon. The tool is designed to be highly flexible. You can type "1530", "15:30", "3:30 pm", or even just "3pm", and the converter will automatically parse your input and display the correct conversions.
Because the calculation runs entirely in your web browser, the conversion is instantaneous. No data is ever uploaded to a server, meaning you can use this tool completely offline once the page has loaded.
How to convert 24 hour to 12 hour time
Converting from 24 hour to 12 hour time is straightforward once you know the rule. The 24-hour clock runs from 00:00 (midnight) to 23:59.
- Morning (00:00 to 11:59): The hours are exactly the same as the 12-hour clock. You simply remove the leading zero if there is one, and add "AM". For example, 08:30 becomes 8:30 AM. The only exception is 00:00, which translates to 12:00 AM (midnight).
- Afternoon and Evening (12:00 to 23:59): For 12:00 to 12:59, just add "PM" (12:30 becomes 12:30 PM). For 13:00 and above, subtract 12 from the hour and add "PM".
If you are ever wondering, "what is 1500 in military time?", simply apply the rule: subtract 12 from 15 to get 3, making it 3:00 PM.
How to convert 12 hour to 24 hour time
Going the other way—from 12 hour to 24 hour time—requires the reverse logic:
- AM Times: If the time is between 1:00 AM and 11:59 AM, keep the hour exactly the same but ensure it is written with two digits. So, 7:15 AM becomes 07:15. For 12:00 AM (midnight) to 12:59 AM, subtract 12 from the hour to get 00 (e.g., 12:45 AM becomes 00:45).
- PM Times: If the time is between 1:00 PM and 11:59 PM, add 12 to the hour. For example, 4:00 PM becomes 16:00. For 12:00 PM (noon) to 12:59 PM, leave the hour as 12 (e.g., 12:15 PM remains 12:15).
Military time follows these exact same rules, but drops the colon entirely. Thus, 16:00 becomes 1600.
Using the military time chart
At the bottom of the tool, you will find a complete military time chart. This quick reference table lists every hour of the day from 0000 to 2300 alongside its 12-hour equivalent.
If you frequently work with international teams, aviation schedules, or healthcare records, glancing at the chart can help you memorize the conversions over time. Eventually, translating 1900 to 7:00 PM or 0800 to 8:00 AM becomes second nature.
Common use cases for military time
While the 12-hour clock is standard for casual use in North America and a few other regions, the 24-hour clock and military time are the global standard for avoiding ambiguity.
Healthcare and Emergency Services. Medical professionals use military time to log patient records, administer medication, and record vital signs. Writing 0200 instead of 2:00 AM ensures there is zero confusion about whether an event happened in the middle of the night or the middle of the afternoon.
Aviation and Logistics. Flights, trains, and shipping schedules almost exclusively rely on the 24-hour clock. A flight departing at 1845 is immediately understood to be an evening flight.
International Communication. If you are scheduling a meeting with someone in Europe or Asia, they will likely use the 24-hour format. Using a converter ensures you don't accidentally schedule a call for 3:00 AM instead of 3:00 PM.
