AM and PM are abbreviations used to denote the time of day in the 12-hour clock system. AM stands for Ante Meridiem, which is Latin for “before midday.” PM stands for Post Meridiem, which means “after midday.”
Here’s a breakdown:
- AM (Ante Meridiem): This period covers the time from midnight (12:00 AM) to just before noon (11:59 AM).
- PM (Post Meridiem): This period covers the time from noon (12:00 PM) to just before midnight (11:59 PM).
Understanding AM and PM helps in distinguishing between morning and afternoon/evening times, especially in regions where the 12-hour clock is commonly used.
