What time does 1:00 PM represent in 24-hour time format?

In the 24-hour time format, which is often used in medical and military settings, 1:00 PM is represented as 1300. This format eliminates confusion between AM and PM by counting hours from midnight.

In this system, the day begins at 00:00 (midnight) and runs until 23:59. From that starting point, the hours continue sequentially. Thus, after 12:00 PM (noon), which is the transition point, the next hour is 13:00, and this continues up to 23:00.

Understanding this format is essential in health care settings, where precise timing can be critical for administering medications or scheduling appointments.
