Uncover The Enigma: Noon AM Or PM?

Author Saxons 29 Jan 2025

The 12-hour clock, also known as the AM/PM system, divides the day into two 12-hour periods: AM (ante meridiem, meaning "before midday") and PM (post meridiem, meaning "after midday"). Noon is the time of day when the sun is at its highest point in the sky, and it is the transition point between AM and PM.

The importance of noon lies in its role as a reference point for daily activities and scheduling. It is typically the time when many people break from work or school for lunch or other midday activities. Noon also serves as a marker for the beginning of the afternoon and the end of the morning.

Historically, noon has been determined by observing the sun's position in the sky. However, with the advent of accurate timekeeping devices, noon is now precisely defined as 12:00 PM.
