13 heures

"13 heures" is the French way of saying 1:00 PM using a 24-hour clock system. Unlike the familiar 12-hour clock, which resets after 12, the 24-hour clock continues counting up to 23:59 before starting over at 00:00. In this system, hours from midnight to noon are numbered 00 to 11, and from noon to midnight are numbered 12 to 23. Therefore, 13 heures corresponds to 1:00 in the afternoon. This format is often used in military, aviation, and scheduling contexts for clarity and precision.
