    The 12-hour system divides the 24 hours of a day into two periods lasting 12 hours each. The first 12-hour period is designated as am. It runs from midnight to noon. The second period, marked pm, covers the 12 hours from noon to midnight. The abbreviations am and pm derive from Latin: 1. AM = Ante meridiem: Before noon 2. PM = Post meridiem: After ...

To convert am or pm t...

    The Egyptians are thought to be responsible for dividing the day into 24 equal parts. One account suggests that this custom evolved because the Egyptians commonly used the base 12, counting the 3 joints in their fingers, not including the thumb. Topics: Timekeeping, Clocks
