Fortnights

A fortnight is a unit of time equal to exactly 14 days (1,209,600 seconds), or two weeks. The word is a contraction of "fourteen nights" from Old English. It is still widely used in British English, particularly in employment law (wages paid fortnightly), rental agreements, and magazine publication schedules. The fortnight has no equivalent single word in most other languages, making it a distinctly British measurement unit.

Weeks

The week is a unit of time equal to exactly seven days (604,800 seconds) with no direct astronomical basis. Its origin is cultural and religious, rooted in ancient Mesopotamian astronomy that associated each day with one of seven celestial bodies visible to the naked eye. The seven-day week spread globally through the Roman Empire and later through Christianity and Islam.
