It shouldn’t surprise you that the term “Happy Hour” originated in  the United States Navy. Back in the 1920’s, the term was slang for the  scheduled time of on-ship performances when the sailors were a little  “happy” from drinking.
However, the act of drinking before dinnertime began around the same  time on-shore due to the Prohibition. Friends would gather for illegal  cocktail hours at speakeasies before they went out to eat since  restaurants could not serve alcohol. In 1959, an article featuring  military life in the Saturday Evening Post made the term more  mainstream.
Over time, happy hour has transitioned from a prelude to an evening  out into more of an after-work ritual. Since the 1980’s, most bars offer  free or discounted appetizers to attendees, attempting to curb drunk  driving.
While happy hour has suffered some controversy and has actually been  banished in certain countries and states, it still exists around the  globe albeit as somewhat of a marketing ploy.
Visit almost any restaurant or bar between 4pm and 7pm on a weekday  and you are likely to find drink and food specials to take the edge off a  long day at the office!
