Facts about AM and PM
The 24-hour clock system, including the use of AM and PM to distinguish between morning and afternoon periods, traces back to the Victorian era in England. However, the concept of dividing time into distinct segments predates this period and has ancient origins. Historical records suggest that ancient civilizations like the Egyptians employed a timekeeping system characterized by long days and short nights, spanning over millennia.
The convention of associating AM with the afternoon period and defining noon falls within this historical context. John Wilkins, a British natural philosopher, notably contributed to this convention in his 1662 essay titled “A Dissertation upon the Source and Nature of the Clock.” In this work, Wilkins utilized the term AM to denote the period surrounding noon, emphasizing its significance in the transition from midnight to morning.
In the opening paragraph of his essay, Wilkins eloquently expressed the notion that the heavens reveal themselves as the sun descends into the astrological sign of Scorpio. This celestial phenomenon symbolizes the critical period between midnight and morning, commonly known as the time of noon.
Conclusion: Understanding the AM Full Form
AM, denoting the period from midnight to noon, holds significance in timekeeping traditions associated with the dawn of a new day. Derived from the Latin term “Ante Meridiem,” meaning “before midday,” AM represents the early hours leading up to noon.
In ancient times, before the widespread use of the hour hand in the 15th century, time was often divided into periods marked by significant celestial events. The designation of AM likely served to differentiate this period from the afternoon and evening hours.
While the exact reason for writing AM twice remains uncertain, both “AM” and “A.M.” are synonymous terms conveying the same meaning. Regardless of the written format, it is essential to accurately interpret and utilize time references to ensure clarity and precision in communication.
