How Military Time Works

Military time (also known as the 24-hour clock) runs from midnight to midnight. Unlike the standard 12-hour clock which repeats the cycle of 1 to 12 twice a day (AM and PM), the 24-hour clock continues counting up after noon.

This format eliminates confusion between "morning" and "evening" hours, making it the standard for emergency services, aviation, healthcare, and the military.

Quick Conversion Rules

• Midnight to 12:59 PM: The hours are mostly the same.
  Exception: 12:00 AM is 00:00.
• 1:00 PM to 11:59 PM: Add 12 to the hour.
  Example: 3:00 PM becomes 15:00 (3 + 12 = 15).
• Say the digits: Read each hour digit before adding "hundred" or "hours" so callouts stay clear over radio or phone.

How to pronounce military time

Military time pronunciation keeps instructions unmistakable. Speak the hour digits first, then tack on the minutes and the word hours. When the minutes are 00, swap in hundred instead.

0800

“Zero eight hundred hours” — morning briefings and job-site roll calls.

1345

“Thirteen forty-five hours” — use the whole 24-hour number after noon, then read the minutes.

1700

“Seventeen hundred hours” — late-afternoon shift change or wrap-up reminder.

0025

“Zero zero twenty-five hours” — include both zeros for just-after-midnight events.

Why use the 24-hour clock?

The primary advantage is precision. In high-stakes environments like hospitals or flight control towers, mistaking 6:00 AM for 6:00 PM could be catastrophic. The 24-hour format (06:00 vs 18:00) leaves no room for ambiguity.
