Not that we need an excuse to celebrate our favorite beverage...

"National Beer Day is a celebration of the Cullen–Harrison Act being signed into law by President Franklin D. Roosevelt on March 22, 1933. Upon signing the legislation, Roosevelt made his famous remark, "I think this would be a good time for a beer." The law went into effect on April 7 of that year, allowing people to buy, sell and drink beer containing up to 3.2% alcohol by weight (or 4.05% by volume) in states that had enacted their own law allowing such sales. People across the country responded by gathering outside breweries, some beginning the night before. On that first day, 1.5 million barrels of beer were consumed, inspiring the future holiday. Today, April 7 is recognized as National Beer Day and April 6 is known as New Beer's Eve."
