Military Time FAQs
What is military time?
Military time, or the 24-hour clock, is a time format that runs from **0000** (midnight) to **2359** (the last minute of the day). It avoids the confusion of AM and PM by using four digits for the hour and minute.
How do I convert standard time to military time?
For PM times (1:00 PM to 11:59 PM), you add 12 to the hour (e.g., $4 \text{ PM} = 1600$). For AM times, you just use a leading zero if needed (e.g., $9 \text{ AM} = 0900$). **Midnight (12:00 AM) is 0000**, and **Noon (12:00 PM) is 1200**.
Why is the 24-hour clock used by militaries and aviators?
The format is critical for high-stakes coordination because it removes all ambiguity. Mistaking 0600 (6 AM) for 1800 (6 PM) could lead to significant operational errors, especially in environments like aviation, military, and medicine.
