The Cullen-Harrison Act allowed for the brewing and sale of beer containing up to 4% alcohol by volume. The act led to the repeal of the 21st Amendment and the end of Prohibition later in the same year.
National Beer Day was officially recognized in a 2017 proclamation by then-Gov. Terry McAuliffe of Virginia.
Other holidays and observances for April 7 include Coffee Cake Day, International Beaver Day, International Snailpapers Day, National Burrito Day, No Housework Day and Public Television Day.
