date "time," early 14c., from O.Fr. date, from M.L. data, noun use of fem. sing. of L. datus "given," pp. of dare "to give, grant, offer," from PIE base *do- "to give" (cf. Skt. dadati "gives," O.Pers. dadatuv "let him give," O.C.S. dati "give," Gk. didomi, didonai, "to give, offer," O.Ir. dan "gift, talent"). The Roman convention of closing every article of correspondence by writing "given" and the day and month -- meaning "given to messenger" -- led to data becoming a term for "the time (and place) stated." Dated "old-fashioned" is attested from 1900.
