Note
A regular plural: fortnight simply adds -s, the way night does. The singular belongs to British, Irish and Commonwealth English and now sounds somewhat dated, and the plural carries that same flavor. It counts whole two-week spans, so a course of four fortnights lasts eight weeks. For readers who find the word unfamiliar, "two weeks" or "eight weeks" says the same thing plainly.
