WHAT'S THE TIME?

 

a.m. - p.m.
a.m. = ante meridiem = the time from midnight to noon = from 00:00 to 12:00
p.m. = post meridiem = the time from noon to midnight = from 12:00 to 24:00
The 24-hour clock is the most commonly used time notation in the world today.
But in English speaking countries the 12-hour clock is the dominant system of time written and spoken.
The 24-hour clock is only used by the military in the United States and Canada.
