National Have a Coke Day is observed worldwide every year on May 8, celebrating the introduction of Coca-Cola, one of the most famous carbonated drinks, which was first sold on this date in 1886 at Jacob’s Pharmacy in Atlanta. The holiday commemorates its inventor, John Stith Pemberton, who initially created the drink as a non-alcoholic alternative to his earlier alcoholic beverage. On this day, millions indulge in Coca-Cola and its various forms, such as floats or cocktails, while sharing their experiences on social media using the hashtag #NationalHaveACokeDay. The Coca-Cola Company, which was formally founded in 1892, continues to keep the drink's formula a closely guarded secret, with only two employees knowing the complete recipe at any given time. Today, Coca-Cola is available in over 200 countries and is commonly served at major restaurant chains.
