Am Pm Full Form

What is the Full Form of AM and PM?

The term AM stands for Ante Meridiem, derived from Latin. This notation is used in the 12-hour clock system to indicate time before noon. AM is associated with the period starting from midnight until noon. It is an essential part of the time standard used worldwide, dividing a day into two segments. The Ante Meridiem period signifies the time before midday, ensuring clarity when referring to the first half of the day.

On the other hand, the full form of PM is Post Meridiem, which refers to the time after noon. Like AM, it is another unit in the 12-hour clock system. Post Meridiem signifies the time from noon to midnight, covering the second part of the day.

Example of AM and PM Usage

When someone mentions arriving at 8 o’clock, it can be confusing without specifying whether it’s morning or evening. The AM and PM system resolves this confusion by denoting morning hours with AM and evening hours with PM. For instance, 8 AM means 8 in the morning, while 8 PM refers to 8 in the evening.

Key Points to Remember:

• AM = Ante Meridiem
  • Ante = before
  • Meridiem = midday (or noon)
• PM = Post Meridiem
  • Post = after
  • Meridiem = midday

The AM and PM system helps in distinguishing between the two halves of the day, ensuring clarity and avoiding confusion.
