AM, or ante meridiem, is a Latin term that refers to the time period before noon. It is commonly used to indicate the hours on a 12-hour clock, with the time period after noon being referred to as PM, or post meridiem.
One of the primary uses of AM and PM is to specify the time of day for various activities, such as appointments, meetings, and events. For example, if you have a doctor’s appointment at 10 AM, you know that it is scheduled for the morning, before noon. Similarly, if you have a meeting scheduled for 7 PM, you know that it is scheduled for the evening, after noon.
In addition to being used to specify the time of day, AM and PM are also commonly used to indicate the relative time of day in relation to the current time. For example, if it is currently 3 PM, you might say that it is “late afternoon.” Similarly, if it is currently 9 AM, you might say that it is “early morning.”
