Legal Drinking Age Day is observed in the United States every July 21. This day was created to highlight the benefits of the minimum legal drinking age of 21 and to encourage responsible drinking. The legal drinking age in the U.S. is notably higher than in many other countries, where it is typically set at 18. The origins of this day are unclear, but it likely references the legal drinking age of 21 and coincides with the birthday of American novelist Ernest Hemingway. Celebrations may include learning about the legal drinking age in various countries, sharing memories of first legal drinks on social media, and teaching children about responsible drinking. The day is also marked by the use of the hashtag #LegalDrinkingAgeDay.
