A fortnight is a unit of time equal to 14
days (two
weeks). The word derives from the
Old English term fēowertīene niht, meaning "fourteen
nights" (or "fourteen days", since the Anglo-Saxons counted by nights).[1][2]
In many languages, there is no single word for a two-week period, and the equivalent terms "two weeks", "14 days", or "15 days" (
counting inclusively) have to be used.
Celtic languages: in
Welsh, the term pythefnos, meaning "15 nights", is used. This is in keeping with the Welsh term for a week, which is wythnos ("eight nights").[5] In
Irish, the term is coicís.
Similarly, in
Greek, the term δεκαπενθήμερο (dekapenthímero), meaning "15 days", is used.
Semitic languages have a "doubling
suffix". When added at the end of the word for "week" it changes the meaning to "two weeks". In
Hebrew, the single-word שבועיים (shvu′ayim) means exactly "two weeks". Also in
Arabic, by adding the common
dual suffix to the word for "week", أسبوع, the form أسبوعين (usbu′ayn), meaning "two weeks", is formed.
Slavic languages: in
Czech the terms čtrnáctidenní and dvoutýdenní have the same meaning as "fortnight".[6] In
Ukrainian, the term два тижні is used in relation to "biweekly, two weeks".
