Most of the clocks that we see are 12-hour clocks. In 12 hour clock, a full
day (i.e. 24 hours) are divided into two parts of 12 hour each. The first part is
known as a.m. or A.M. (ante meridian), which means before noon {i.e. time
between midnight (0:00) & noon (12:00)} and second part is known as p.m.
or P.M. (post meridian), which means after noon {i.e. time between noon
(12:00) & midnight (0:00)}.
Technically, midnight and noon, each hour of the day is suffixed by am or
pm to identify whether the hour is being referred is the morning, afternoon
or evening. But most digital clocks show 12 am and 12 pm to specify
midnight and noon, respectively.
We generally use 12 hours clock time in which hour hand takes two round
of the face of the clock in 24 hours.
