Is Afternoon 12 AM or PM?
‘Noon’ means ‘midday’ or 12 in the afternoon. The standard way of writing this therefore would be 12pm. However, there are ways to avoid the confusion completely: you could write 12 noon or 12 midnight instead.
Is the sun at its peak at noon?
Solar noon is the time when the Sun appears to contact the local celestial meridian. This is when the Sun reaches its apparent highest point in the sky, at 12 noon apparent solar time and can be observed using a sundial. The local or clock time of solar noon depends on the longitude and date.
Does 12pm come after 11am?
As standard 12:00 AM is taken as the start of the day. Time of the day is divided in two halves (24hour= 12 hours before midday + 12 hours after midday) so the 11 AM is 11th hour before midday as clock strikes 12 again it changes to PM (after midday) so it’s 12 PM after 11 AM and 12 AM after 11 PM.
Why is 12pm not 12am?
“a.m.” means “ante meridiem” which means “before midday” and p.m. means “post meridiem”, which means “after midday”. Consequently to use am/pm to refer to midday, (12noon) is simply wrong (and similarly midnight). The correct terms are 12 noon and 12 midnight, with times in between using am/pm.
Why is 12pm before 1pm?
The older Latin expression means “after midday” or after noon (afternoon). The PM is needed as soon as the clock chimes 12 o’clock because exactly at one minute past 12:00, i.e. 12:01 p.m., it is one minute after midday.
Why does the clock start at 12 instead of 1?
Since the highest point of the day was noon, the opposite has to be midnight that was when the 12 started over again, so that’s why the day starts at midnight. The reason that the hands on a clock travel the way they do, or “clockwise,” also goes back to the invention of the sundial in ancient Egypt.
