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, he 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 is, however, 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" organised "semi-weekly smokers" onboard. 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. The Random House Dictionary of American Slang dates "Happy hour," as a term for afternoon drinks in a bar, to a Saturday Evening Post article on military life in 1959. The article detailed the lives of government contractors and military personnel who worked at missile-tracking facilities in the Caribbean and the Atlantic. "Except for those who spend too much during 'happy hour' at the bar – and there are few of these – the money mounts up fast." Barry Popick's online etymology dictionary, The Big Apple, lists several pre-1959 citations to "Happy Hour" in print, mostly from places near Naval bases in California, from as early 1951.
Regulations
Canada
The Province of Alberta created restrictions to happy hours that took effect in August 2008. All such promotions must end at 8:00 p.m, and drink prices must conform to the Alberta Gaming and Liquor Commission's minimum price regulations at all times. In Ontario, while establishments may vary liquor prices as long as they stay above the minimum prices set by the Alcohol and Gaming Commission of Ontario, they are not permitted to advertise these prices "in a manner that may promote immoderate consumption." In particular, the phrase "happy hour" may not be used in such advertisement.
Ireland
Happy hour has been illegal in the Republic of Ireland since 2003, under the Intoxicating Liquor Act.
Netherlands
The KHN, a hospitality sector lobby group, has agreed with its members to stop happy hours to discourage binge drinking by youth, but only if the government would vote to not raise the minimum drinking age. In March 2013, the law to raise the drinking age to 18 was passed.
United Kingdom
The National Mandatory Licensing Conditions introduced in 2010 required "all reasonable steps" to be taken to prevent irresponsible drinks promotions which effectively banned traditional happy hours. Under the 2014 revision to these conditions, the licensee "must ensure" such promotions do not take place, although there is a subjective test, that takes account of the kind of establishment and its track record, for any promotions that offer unlimited or unspecified alcohol free or for a fixed or discounted fee.
In 2004 Glasgow banned happy hours to reduce binge drinking.
United States
was one of the first U.S. states to implement a statewide ban on happy hours in 1984. Other U.S. states also have similar restrictions. The reason for each ban varies, but include: to prevent drunk driving, avoid the nuisance to neighbors from loud crowds and public drunkenness, and to discourage unhealthy consumption of a large amount of alcohol in a short time. In 1984, the U.S. military abolished happy hours at military base clubs. In 2011, the Utah State Legislature passed a ban on happy-hours, effective on 1 January 2012. In July 2011, Pennsylvania extended the period of time for happy hour from two hours to four hours. In June 2012, happy hour became legal in Kansas after a 26-year ban. In July 2015, a 25-year happy hour ban was ended in Illinois. , happy hour bans existed in Alaska, Delaware, Hawaii, Indiana, Maine, Massachusetts, North Carolina, Oklahoma, Rhode Island, Utah, and Vermont.
