AM (Ante Meridiem) Definition
The word a.m is derived from the Latin word “Ante Meridiem” which means a time before noon. This period begins from midnight to midway or noon.
This half a day starts at midnight, also known as 12 a.m, and remains one minute before noon, also known as 12 p.m.
Moreover, we say this half of the day from midnight to midday as the morning. In contrast, the time that starts from noon to midnight is known as p.m.
For example, if it’s five in the morning, it will be called 5 a.m, or if it is five in the evening, it will be called 5 p.m. For more precise understanding, check out the diagram listed below:
