National Happy Hour Day is celebrated annually on the third Friday of November. This day encourages people to unwind and enjoy socializing with friends and family over drinks and appetizers. Many bars and restaurants offer special promotions and discounts to attract customers during this time. The concept of happy hour originated in the early 20th century, initially referring to a scheduled time for entertainment and relaxation. Today, it has evolved into a popular social event, where people gather to enjoy a variety of beverages and food in a casual atmosphere.
