Ooh I never knew it's from Latin. Thanks so much for  the information 

Answer 2

it is quite obvious lol am means Daylight (morning) and pm means Midnight (afternoon). There is no deeper way to explain I don't think anyway lol but there you go hopefully that helped lol.

Answer 3

From the Latin words meridians (midday), ante(before), and the term antemeridian (a.m) means before midday, and post meridiem ( p.m) means after midday.

Answer 4

A.M stands for Ante Meridiem means before mid day (before 12AM )and P.M stands for Post Meridiem means after mid day (after 12 AM). These two words are Latin words.

Answer 5

 am stands for ante-meridiem which is before the Sun has crossed the meridian line and pm stands for post-meridiem which is fter the Sun has crossed the meridian line. 

AM is before noon. PM is after midday. AM is midnight to Noon and PM is Noon to Midnight. 

Answer 6

A.M means Ante meridiem it means before midday(before 12 ) and P.M. means post meridian as post means after so it refers to after midday(after 12)

Answer 7

A.M. and P.M. stands for "ante meridiem" and "post meridiem" respectively. They are Latin terms used to denote when something occurs during the day. A.M. is used to refer to the time period between midnight and noon, while P.M. is used to refer to the time period between noon and midnight. As with most timekeeping systems, the 24-hour clock is used to measure time throughout the world.

Answer 8

A.M stands for ante Meridien translating to ''before midday'' while P.M stands for post Meridien translating to "after midday".

Answer 9

a.m. is short for the Latin ante meridiem, meaning “before noon,” which refers to the period from midnight until noon. And, p.m. then? It's short for the Latin phrase post merīdiem meaning “after noon.” Got it. One minute after noon is 12:01 p.m.

Answer 10

From the Latin words meridians (midday), ante(before), and the term antemeridian (a.m) means before midday, and post meridiem ( p.m)
