Using the 24-hour Clock: What's the Time?

Remember that 24 hour clock time uses 4 numbers separating the hours from the minutes with a : sign.

Also, after 12:00 pm on the 24 hour clock, continue counting into the teens and twenties for the hours: 13 (1pm) all the way to 24 (12 midnight).

7.35 a.m. is 07:35

7.35 p.m. is 19:35

Example

What 24 hour clock time is 46 minutes after 7.35 p.m.?

Answer

We start on the hour at 7.00 p.m. and then add 46 minutes and 35 minutes from the question.

35 + 46 = 81 minutes.

81 minutes is 1 hour (60 minutes) and 21 minutes.

1 hour and 21 minutes after 7.00 p.m. is 8.21 p.m.

8.21 p.m. is 20:21 in 24 hour clock time.
