The 24 Hour Clock

Converting 24 Hour Times

Converting from 24 hour times to 12 hour times

The following simple steps will help you change a 24 hour time to a 12 hour time with 'am' and 'pm'.

• If the hour is exactly 12, then simply label it as a pm time.
• If the hour is 00, then change it to 12 and label it as an am time.
• If the hour is greater than 12, then simply subtract 12 from the hour and label it as a pm time.
• Otherwise, simply label it as an am time and take away any leading zeros.

The minutes and seconds never change when changing between 24 hour and 12 hour times.

Examples

14:36 = 2:36pm     02:12 = 2:12am

09:24 = 9:24am     17:48 = 5:48pm

00:45 = 12:45am     12:15 = 12:15pm

20:36 = 8:36pm     23:56 = 11:56pm

Converting from 12 hour times to 24 hour clock

The following simple steps will help you change a 12 hour time to a 24 hour time.

• If the hour is exactly 12pm, then simply remove the 'pm' label.
• If the hour is 12am, then change it to 00.
• If the hour is a pm time, then simply add 12 to the hour.
• Otherwise, the hour does not change. If it is less than 10, then add a zero before the digit.

The minutes and seconds never change when changing between 24 hour and 12 hour times.

Examples

1:45am = 01:45     1:45pm = 13:45

4:20am = 04:20     4:20pm = 16:20

11:32am = 11:32     11:32pm = 23:32

12:07am = 00:07     12:07pm = 12:07
