An hour consists of 60 minutes, and a minute consists of 60 seconds, while a second is defined scientifically based on atomic vibrations. As there are 24 hours in a day, most people use a 12-hour clock or a 24-hour clock to read the time.
12-hour clock: A 12-hour clock uses numbers 1-12. Analog watches do not have indications of whether the time is morning or evening, while digital watches have the terms "AM" and "PM." AM denotes before noon, while PM denotes afternoon, which reduces ambiguity.
24-hour clock: A 24-hour clock uses numbers 00-23 and 00:00 indicates midnight. It is also referred to as military time in some countries. The time from 00 to 11 denotes AM hours, while 12 to 23 denotes PM hours. It is an international standard time which is used where time tracking is important.
