Coast Guard Practice Exam 2026 – Complete Prep Guide

In military time, the hours of the day are represented in a 24-hour format, which eliminates the need for "AM" and "PM" designations. To convert standard time to military time, you add 12 to any hour that is after noon. For 3:00 PM, it falls in the afternoon, so you would add 12 to the hour.

Thus, 3:00 PM becomes 15:00 in military time. This is why the representation of 3:00 PM in military time is 1500. Understanding this concept is crucial for operations where precise time notation is essential, such as in military, aviation, and maritime contexts.
