Is there a law about buying alcohol on your 21st birthday in California?
The Right Answer is:
The day before your birthday, you are allowed to buy alcohol! Most stores, on the other hand, are unaware of this and will wait until your birthday to sell to you. Furthermore, some liquor stores will not sell to you until the day after your birthday because they are frightened of being discovered selling to minors. Simply go to a pub and the first one will be purchased for you by your friendly bartender!
