Showing the Time

There are two major ways to show the time: “AM/PM” or “24 Hour Clock”.

With the 24 Hour Clock the time is shown as how many hours and minutes since midnight.
With AM/PM (or “12 Hour Clock”) the day is split into the 12 Hours running from Midnight to Noon (the AM hours) and the other 12 Hours running from Noon to Midnight (the PM hours).
