AM stands for "Ante Meridiem", which is Latin for "before midday".
It is used to denote the period of time from midnight (12:00 AM) to noon (12:00 PM).
The opposite of AM is "PM", which stands for "Post Meridiem", meaning "after midday".
The 12-hour clock system, which uses AM and PM, is commonly used in many countries, including the United States.
Here are some examples of how AM is used:
- 8:00 AM: This refers to 8 o'clock in the morning.
- 11:59 AM: This refers to one minute before noon.
