Inclusive counting
Inclusive counting is usually encountered when dealing with time in the Romance languages. In exclusive counting languages such as English, when counting "8" days from Sunday, Monday will be day 1, Tuesday day 2, and the following Monday will be the eighth day. When counting "inclusively," the Sunday (the start day) will be day 1 and therefore the following Sunday will be the eighth day. For example, the French phrase for "fortnight" is quinzaine (15 [days]), and similar words are present in Greek (δεκαπενθήμερο, dekapenthímero), Spanish (quincena) and Portuguese (quinzena). In contrast, the English word "fortnight" itself derives from "a fourteen-night", as the archaic "sennight" does from "a seven-night"; the English words are not examples of inclusive counting.
