Modesto Police Department Explorers Training Practice Test

The representation of 1 AM in military time is 0100. Military time uses a 24-hour clock format, where hours are counted from 00 to 23. In this system, 1 AM is shown as 01:00. The first two digits indicate the hour, and in this case, '01' signifies one hour past midnight. This format eliminates ambiguity between AM and PM times, making it clearer for scheduling and communication, especially in military and emergency services contexts.

The other times listed correspond to different hours: 1100 represents 11 AM, 1200 represents noon (12 PM), and 2300 represents 11 PM. Therefore, 0100 is the only correct option for 1 AM.
