FAQ
What is military time?
Military time is another name for the 24-hour clock: a full day runs from 00:00 to 23:59 with no AM/PM label, so every hour has one unique number. It is used by the armed forces, hospitals, airlines and train schedules worldwide to avoid mixing up morning and evening times.
Is 12 AM midnight or noon?
12 AM is midnight, which is 00:00 in 24-hour (military) time. 12 PM is noon, which is 12:00 — this pair is the single most common mix-up when reading a 12-hour clock.
How do I convert 12-hour AM/PM time to 24-hour format?
Keep AM hours as they are, except 12 AM which becomes 00. For PM hours, add 12 to the hour, except 12 PM which stays 12. For example, 7:30 AM becomes 07:30, and 7:30 PM becomes 19:30.
