In 24-hour time, what is 10:00am?

• A. 1000hrs
• B. 1200hrs
• C. 1100hrs
• D. 1300hrs

Answer: (A)

Converting 10:00 AM into 24-hour time format involves a straightforward process. In the 24-hour clock system, hours are represented from 00 to 23, where 00:00 signifies midnight, and the hours advance throughout the day until 23:00, which is 11:00 PM. For AM times from midnight to noon, the conversion is simply done by adding a leading zero if necessary. Since 10:00 AM is after midnight but before noon, it remains the same numeric value, resulting in 10:00 AM being expressed as 1000 hours in 24-hour time notation. Thus, the correct representation is indeed 1000 hours. This format is commonly used in military and various professional contexts to avoid confusion between AM and PM times.
