## 24 hour time

TPS: When have you seen 24 hour time used in society?

Is midnight 12 a.m. or 12 p.m.

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
