Tomorrow, April 7th, is "National Beer Day" in the United States, which commemorates the return of legal beer sales in 1933, the first step in the repealing of prohibition, which officially occurred on December 5, 1933 with the passage of the 21st Amendment.
But if you don't want to wait, TODAY is "New Beer's Eve":
