Get ready for some all-day happy hours on your favorite beers this Saturday -- it’s National Beer Day 2018.

Breweries, bars and restaurants across the U.S. are offering beer deals and free beer tastings on April 7 in honor of National Beer Day.

The unofficial annual observation has an interesting backstory as to why it’s celebrated on April 7. It turns out that date was chosen for National Beer Day to pay homage to President Franklin Delano Roosevelt signing the Cullen-Harrison Act into action. The 1933 law legalized the buying, selling and drinking of beer and wine for the first times since Prohibition took over the U.S. in 1920. Prohibition of all alcohol officially came to an end with the ratification of the 21st Amendment, but Roosevelt’s signature nearly eight decades ago still carries weight today.
