Is there a law about buying alcohol on your 21st birthday in California?
The Right Answer is:
It is permitted to purchase alcohol the day before your birthday! Most places, however, are unaware of this and will not sell to you until your birthday. Furthermore, some liquor outlets are so afraid of being caught selling to minors that they will not sell to you until the day after your birthday. Simply go to a pub and your friendly bartender will purchase the first one for you!
