The day you were born
You can't gamble or drink until your birthday when you turn 21. You also need to carry your ID with you even if you're not drinking and gambling you can get thrown out of a casino if you don't have an ID on you
It is the exact date, meaning you can't gamble until your 21st birthday, not even the day before, even if it is like 11:59 pm the day before your 21st birthday. I have lived here my whole life so I know the law very well. Also make sure you have your ID with you at all times, because these Casinos in this town will not "take you for your word", and they will not be nice about it either.
