History of the Fortnight and Year
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.
Calendars have been developed since antiquity to track the seasons, crucial for agriculture. Early calendars (e.g., Egyptian) approximated the solar year. The Julian calendar introduced the leap year concept (every 4 years) to better align with the ~365.25 day solar year. The Gregorian calendar refined this further by adjusting the leap year rule (skipping leap years in century years not divisible by 400) for even greater accuracy relative to the tropical year (time between vernal equinoxes).
