1. coexistent, concurrent, simultaneous. Contemporary, contemporaneous, coeval, coincident all mean happening or existing at the same time. Contemporary often refers to persons or their acts or achievements: Hemingway and Fitzgerald, though contemporary, shared few values. Contemporaneous is applied chiefly to events: the rise of industrialism, contemporaneous with the spread of steam power. Coeval refers either to very long periods of time—an era or an eon—or to remote or long ago times: coeval stars, shining for millenia with equal brilliance; coeval with the dawning of civilization. Coincident means occurring at the same time but without causal or other relationships: prohibition, coincident with the beginning of the 1920s.
