How 12-Hour to 24-Hour Conversion Works

The 12-hour clock uses AM and PM to distinguish between the first and second halves of the day. The 24-hour clock represents the same day using hours from 00 through 23.

AM times For most AM times, the hour remains the same. For example, 8:15 AM becomes 08:15.

PM times For PM times from 1 PM through 11 PM, add 12 to the hour. For example, 7:30 PM becomes 19:30.

12:00 AM Midnight is represented as 00:00 in 24-hour time.

12:00 PM Noon remains 12:00 in 24-hour time.

When Is This Converter Useful?

A 12-hour to 24-hour converter is useful whenever a schedule, timetable, form, application, device, or technical system expects 24-hour time while your source time is written with AM or PM.

Schedules and timetables

Quickly convert departure, arrival, class, appointment, or event times into a 24-hour format.

International time notation

24-hour notation is widely used in schedules and digital systems, making conversion useful when working with information presented in different time formats.

Data entry

Common Mistakes to Avoid

• Adding 12 to 12 PM: 12 PM is 12:00, not 24:00.
• Treating 12 AM as 12:00: Midnight is 00:00 in 24-hour notation.
• Forgetting the leading zero: 6:15 AM is normally written as 06:15 in a two-digit 24-hour format.
• Changing the minutes: The conversion changes the hour representation; the minutes stay the same.
