Question

About AM and PM ?????​

Answer 1

$\bold{ANSWER}$

A.M stands for anti meridian. 

• P.M stands for post meridian. 

• AM is the time before noon ( before 12o'clock)

• PM is the time after noon ( after 12'o clock ) 

• The terms AM and PM derive from Latin words : 

→ Meridies

→ Post 

→ Ante 

• Meridies means midday ( 12 o'clock ) 

• Post means after.

• Ante means before. 

So, 

• Ante Meridies —⟩ Anti meridian —⟩ Before noon.

• Post Meridies —⟩ Post meridian —⟩ After noon 

• AM covers the time from 12a.m. to 11.59a.m. 

• PM covers the time from  12p.m. to 11.59p.m.

AM means Ante Meridian
