In American English, 1300 hours would be described as which designation?

• A. Morning
• B. Afternoon
• C. PM
• D. Evening

Answer: (C)

Understanding the time labeling used with clocks is key here. In American English, times from 12:00 noon to just before midnight use the designation PM, while times from midnight to just before noon use AM. 1300 hours is 13:00 in 24-hour time, which is after noon, so it becomes 1:00 PM in 12-hour time. That’s why PM is the correct designation. Morning is before noon, so it doesn’t fit. Evening comes later in the day, typically after late afternoon, so that’s not appropriate for 1:00 PM. Afternoon is a general period of the day, but the specific clock designation for 1:00 PM is PM.
