Happy hour is a marketing term for a period of time in which a venue (such as a restaurant, bar, bowling alley, stadium, or state or county fair) offers discounts on alcoholic drinks, such as beer, wine, and cocktails. Free Hors d'oeuvres, appetizers and discounted menu items are often served during Happy hour.
The words "happy" and "hour" have appeared together for centuries when describing pleasant times. In act I, scene 2 of William Shakespeare's King Henry V (said to have been written in about 1599), for example, King Henry says, "Therefore, my lords, omit no happy hour That may give furtherance to our expedition . . . ." The use of the phrase, "Happy Hour," to refer to a scheduled period of entertainment, however, is of much more recent vintage.
One possible origin of the term "Happy Hour," in the sense of a scheduled period of entertainment, is from the United States Navy. In early 1913, a group of "home makers" called the "Happy Hour Social" organized "semi-weekly smokers" on board USS Arkansas. The name "Happy Hour Club," "Happy Hour Social Club," and similar variants, had been in use as the names of social clubs, primarily by women's social clubs, since at least the early 1880s. By June 1913, the crew of Arkansas had started referring to their regularly scheduled smokers as "Happy Hours." The "Happy Hours" included a variety of entertainment, including boxing and wrestling matches, music, dancing and movies. By the end of World War I, the practice of holding "Happy Hours" had spread throughout the entire Navy.
The idea of drinking before dinner has its roots in the Prohibition era. When the 18th Amendment and the Volstead Act were passed banning alcohol consumption, people would host "cocktail hours", also known as "happy hours", at a speakeasy before eating at restaurants where alcohol could not be served. Cocktail lounges continued the trend of drinking before dinner.
