National Happy Hour Day is observed worldwide on November 12, providing an opportunity for friends to gather and enjoy discounted drinks at various bars and restaurants. The origins of the holiday are unclear, but the term "happy hour" dates back to at least Shakespearean times and became associated with social gatherings in the late 1880s. It gained popularity in the U.S. Navy after World War I, where scheduled entertainment periods were referred to as happy hours. The modern concept of happy hour, offering reduced prices on drinks, emerged in the 1950s, although some states have implemented bans on such promotions to combat issues like binge drinking. Despite these restrictions, happy hours remain a popular custom in many places, with some venues offering alternative promotions like "buy one get one free." Participants are encouraged to share their experiences on social media using hashtags related to the day.
