Fortnight

A fortnight is a measure of time equivalent to two weeks: that is 14 days, or literally 14 nights. The term is most commonly used in the UK. It derives from the archaic fort meaning fourteen.

In the VMS operating system, some configuration parameters are specified in microfortnights (one millionth of a fortnight, or approximately 1.2096 seconds). Millifortnights (about 20 minutes) and nanofortnights (1.2096 milliseconds) have also been used occasionally in computer science, usually in an attempt to be deliberately over-complex and obscure. The aim is generally to slow users down, to allow them to set parameters, but only after some thought.
