What is a Fortnight and a Century?
A fortnight is a unit of time equal to exactly two weeks, which corresponds to 14 days or 336 hours.
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.
Note: The Fortnight is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Century belongs to the imperial/US customary system.
History of the Fortnight and Century
The word "fortnight" originates from the Old English term "fēowertīene niht," meaning "fourteen nights." Counting periods by nights was common among ancient Germanic peoples. The term has been in continuous use in English for centuries and remains relatively common in the United Kingdom, Ireland, Australia, New Zealand, and some other Commonwealth countries, although its usage has declined somewhat in favor of "two weeks," especially in North America.
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.
