“PM” usually means post meridiem, which is the time from noon to midnight in the 12-hour clock system. People also use “PM” to mean prime minister in some contexts, but in everyday time-related use, it means the afternoon and evening hours.
In daily life, people use “PM” when writing or saying the time, like 3:00 PM or 8:30 PM. It helps show whether a time is before or after noon, so there is no confusion. If someone says “Let’s meet at 6 PM,” they mean six in the evening.
