Origin of 'a.m.'
The Latin term 'ante meridiem' translates to 'before midday' in English. The concept of dividing the day into two 12-hour periods, a.m. and p.m., dates back to ancient civilizations like the Egyptians and Greeks. The use of a.m. became standardized in the modern era with the adoption of the 12-hour clock system.
