Introduction
Have you ever wondered what AM or PM means? These two acronyms are commonly used to indicate time, but their meanings are not always clear, especially if English is not your first language. In this article, we will explain the meaning of AM and PM, and how to use them correctly.
What Does AM Mean?
AM stands for "ante meridiem" in Latin, which means "before noon." It refers to the period of time from midnight to noon. For example, 10:00 AM means 10 o'clock in the morning.
In most countries, the 24-hour clock is used in official documents and communication, but the 12-hour clock with AM and PM is more commonly used in daily life. It is important to note that the 12-hour clock starts over at noon, so 12:00 PM is noon, not midnight.
What Does PM Mean?
PM stands for "post meridiem" in Latin, which means "after noon." It refers to the period of time from noon to midnight. For example, 10:00 PM means 10 o'clock at night.
Just like with AM, the 12-hour clock is more commonly used in daily life, and the 24-hour clock is used in official documents and communication. It is important to remember that midnight is 12:00 AM, not 12:00 PM.
