Military Time Converter

Convert between 24-hour and 12-hour clock notation for time cards.

Enter values, then select Calculate.

Worked example

1730 means 17:30 in a 24-hour clock and 5:30 PM in a 12-hour clock. 0000 is midnight; 1200 is noon.

A time conversion does not tell you whether a shift crosses midnight. Compare start and end with the actual dates on your time record.

Is 2400 accepted?

Use 0000 for midnight in this calculator.

What is 9:00 PM in 24-hour time?

21:00. Add 12 to the hour for PM times except 12 PM.
