clocks in general
Clocks in general have 12 or 24 hours, 60 minutes in every hour, and 60 seconds in every minute.
in a 12 hour clock there are really 24 hours, 12 hours from midnight to noon and 12 hours from noon to midnight.
to convert 12-hour time to 24-hour time, you need to do 2 things:
- for the range of 1pm to 12am, add 12 to the hour.
- for the range of 12am to the the time just before 1am (12:59:59am), subtract 12 from the hour.
In a 24-hour clock there are still 24 hours,
The time immediately after 24h 00 is 0h 01 through 0h 59. 24h and 0h converts to 12:00am, because 24h and 0h are the same position on a 24hour clock. The time from 12h 00 through 12h 59 converts to 12:00pm through 12:59pm.
To convert 24-hour time in the 13h to 24h range, subtract 12 from the hour.
