How do you calculate 24 hour time?

24-hour clock
After midday, you simply add 12 to the the number of hours that have passed. For example: 3:00 p.m. is 3 hours after 12:00 p.m. (midday). 3 p.m. + 12 hours = 15:00. 8:30 p.m. is 8 hours 30 minutes after 12:00 p.m. 8 hours 30 minutes + 12 hours = 20:30.

Why do we have a 12 hour clock?

Why do we use the a.m.-p.m. system for telling time? Anyway, as near as I can tell, the 12-hour clock goes way back to ancient Mesopotamia and Egypt. The Egyptians used a 12-hour sundial to tell time during the daytime and a 12-hour water clock at night. The Romans also used a 12-hour clock.
