Etymology

Origin of contemporaneous

First recorded in 1650–60; from Latin contemporāneus, equivalent to con- con- + tempor- (stem of tempus “time”) + -āneus ( -ān(us) -an + -eus -eous )

Explanation

If you're born on the same day as your friend, you've got a contemporaneous birthday, or one that happens in the same period of time. Contemporaneous comes from the Latin prefix con- meaning "together with" and temporaneus, meaning "time." Two contemporaneous events happen together in time. Richard Nixon's presidency and the first man on the moon are contemporaneous — both happened at the same period of time in history.
