Using a.m. and p.m.
We know that the period from one midnight to next midnight is called a
day. The hour hand completes two rounds on the dial in a day. It means it
takes 24 hours to complete a day. Thus, the clock shows the same time twice
a day. See the figures of a clock.
The time is 6 o’clock. So, how do we know whether
it is 6 in the morning or 6 in the evening ?
The time from 12 midnight to 12 noon is called a.m. and the time from 12
noon to 12 midnight is called p.m.
The full form of a.m. is ante-meridian and p.m. is post-meridian .
Instead of writing 12 a.m. or 12 p.m. We write 12 noon or 12 midnight.
