What is AM and PM?
AM and PM are abbreviations that help us differentiate between the two halves of the day in a 12-hour clock system. "AM" stands for Ante Meridiem, indicating the time from midnight to noon, while "PM" stands for Post Meridiem, covering the time from noon to midnight. This division allows us to specify whether we're referring to morning or evening hours, preventing misunderstandings in scheduling and communication.
Understanding Ante Meridiem (AM)
Ante Meridiem, or AM, signifies the hours between midnight (12:00 AM) and noon (11:59 AM). During this time, the sun rises in the sky, marking the beginning of a new day. Activities during AM hours typically include morning routines, commuting to work or school, and early-day business operations.
Understanding Post Meridiem (PM)
Post Meridiem, or PM, refers to the hours between noon (12:00 PM) and midnight (11:59 PM). These hours encompass the afternoon and evening, when the sun sets and nighttime begins. PM hours are often associated with lunch breaks, evening activities, and winding down the day.
Historical Origins of AM and PM
