fortnights

A fortnight is a unit of time equal to fourteen nights and fifteen days. The word fortnight is a portmanteau of the Old English "fēowertīene niht," meaning "fourteen nights." It is commonly used in the United Kingdom, Ireland, and other Commonwealth countries to describe periods of time, particularly in the context of work schedules, holidays, or recurring events. For example, a contract might be for a duration of four fortnights, or a bi-weekly magazine is published every fortnight.

Historically, the fortnight was a significant unit of time for various cultural and religious observances. Many agricultural societies operated on a fortnightly cycle, and some religious calendars incorporated fortnightly intervals. The concept of a fortnight has also appeared in literature and popular culture, often associated with periods of courtship or significant events. In modern usage, while less common than weeks or months, the fortnight remains a recognized and utilized measure of time, providing a convenient intermediate duration between shorter and longer periods. Its usage tends to be more prevalent in certain regions and within specific contexts, maintaining its relevance in everyday language.
