National Beer Day is celebrated in the United States every year on April 7, marking the day that the Cullen–Harrison Act was enacted after having been signed into law by President Franklin D. Roosevelt on March 22, 1933. This led to the Eighteenth Amendment being repealed on December 5, 1933, with ratification of the Twenty-first Amendment to the U.S. Constitution. April 6, the day prior to National Beer Day, is known as New Beer’s Eve.
National Beer Day was first created in 2009 by Justin Smith of Richmond, Virginia. After much prodding from his friend, Mike Connolly, Smith started a Facebook page that was noticed by Colorado Beer Examiner, Eli Shayotovich. Smith’s promotion of the new holiday via various social media outlets was rewarded when the beer drinking app, “Untappd”, created a badge for National Beer Day that rewarded participants that checked a beer into the app on April 7. National Beer Day has since been trending every year on April 7 using the hashtag #NationalBeerDay.
