Carpe diem is a Latin aphorism, usually translated "seize the day", taken from book 1 of the Roman poet Horace's work Odes (23 BC). Translation. Carpe is the second-person singular present active imperative of carpō "pick or pluck" used by Horace to mean "enjoy, seize, use, make use of". Diem is the accusative of dies "day". A more literal translation of carpe diem would thus be "pluck the day [as it is ripe]"—that is, enjoy the moment. It has been argued by various authors that this interpretation is closer to Horace's original meaning.
