Firefighter 1C Wildland Practice Exam

In a 24-hour clock system, the hours are counted from 00:00 (midnight) to 23:59. This system eliminates the need for "AM" and "PM" designations.

1 PM in a 24-hour format is represented by adding 12 to the hour of 1. Therefore, 1 PM translates to 13:00. The counting progresses as follows:

- From midnight (00:00) until 1 PM, the hours 1 through 12 retain their numerical values.

- When reaching 1 PM, the hour changes to 13, continuing through to 23 for the remaining hours of the afternoon and evening.

This understanding of the conversion process clearly establishes why 1 PM corresponds to 1300 in military time.
