PM is an abbreviation for "post meridiem," derived from Latin, meaning "afternoon" or "after midday." It is used to indicate the time of day after 12:00 noon until midnight in the 12-hour clock system. The term PM is commonly used to distinguish between the two halves of the 24-hour day, where AM signifies the time between midnight and noon.
This time notation is predominantly used in English-speaking countries and in countries that follow the American standard. In the PM time format, the numbering convention starts at 12:00 PM (noon), followed by 1:00 PM, 2:00 PM, and so on, up until 11:59 PM, which represents the last minute before midnight.
PM is typically utilized in schedules, timetables, and various everyday contexts like making appointments or stating event start times. It is also employed in various professional fields such as transportation, the medical sector, and event planning to avoid confusion arising from the 24-hour clock format.
Additionally, the term PM can refer to "prime minister," which signifies the head of government or executive branch in a parliamentary system. This usage is common in political contexts and often carries specific country-specific connotations. The responsibilities and powers of a prime minister may vary between countries, depending on the political structure and individual constitutional arrangements.
"PM" is an abbreviation of the Latin term "post meridiem", which translates to "after noon" in English. It comes from the division of a day into two halves, morning (ante meridiem, "before noon") and afternoon (post meridiem). The use of "am" and "pm" to differentiate between the two halves of the day is believed to have originated in medieval monastic communities, where they needed a precise way to track time for their daily prayers and activities. The use of "am" and "pm" was later adopted more widely for general timekeeping purposes.
