What is AM?

Ante Meridiem(AM) is the Latin phrase for “before midday”. It is used to describe the period of time before noon. The term can be used in a few different ways.

Some people use Ante Meridiem to describe the period of time from midnight to noon. This is technically incorrect, as the term actually refers to the hours before noon.

Others use Ante Meridiem to describe the period of time from sunrise to noon. This is a more accurate use of the term, as it refers to the hours before noon when the sun is up.

Still others use Ante Meridiem to describe the period of time from 6:00 am to noon. This is also a more accurate use of the term, as it refers to the hours before noon when most people are awake and active.

No matter how you use it, Ante Meridiem simply refers to the hours before noon. So, if you’re wondering what time it is, and someone tells you it’s 10:00 AM, they’re telling you that it’s 10:00 in the morning.
