Determine Time Format
Earlier than performing any calculations, it is important to establish the format of the time values you are working with. Frequent time codecs embrace:
-
12-Hour Format (AM/PM)
This format shows time in a 12-hour cycle, utilizing the designations AM (ante meridiem) for instances earlier than midday and PM (submit meridiem) for instances after midday. For instance, 9:30 AM or 4:15 PM.
-
24-Hour Format
Also referred to as army time, this format shows time utilizing a 24-hour clock, starting from 00:00 to 23:59. For instance, 09:30 or 16:15.
