What is a Century and a Week?
A century is a unit of time equal to 100 consecutive years. It is widely used for marking long periods, especially in historical contexts and for discussing long-term trends.
A week is a unit of time equal to seven days. It is not an SI unit but is widely used as a convenient cycle for organizing activities longer than a day but shorter than a month.
Note: The Century is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Week belongs to the imperial/US customary system.
History of the Century and Week
The word "century" derives from the Latin "centum," meaning one hundred. In ancient Rome, a centuria was initially a military unit of about 100 soldiers. The application of the term to a period of 100 years became common with the development and standardization of calendar systems, particularly the Julian and Gregorian calendars, used for historical dating.
The seven-day week has origins in ancient Babylonian astronomy, linked to the seven classical celestial bodies visible to the naked eye (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn). This system was adopted by the Jews and later spread through Christianity and Islam. While other cultures have used different week lengths throughout history, the seven-day week became dominant globally, particularly with the adoption of the Gregorian calendar.
