Abc Alcohol California In The State Of Virginia, Can You Purchase Alcohol From The ABC Store The Day Before Your 21st Birthday?

In the state of Virginia, can you purchase alcohol from the ABC store the day before your 21st birthday? - abc alcohol california

In the ABC store, my friend was allowed to buy alcohol the day before his 21st Birthday, but his birthday fell on a Sunday. I was not sure if it just because they are closed at this time permitted for the purchase of a day or if it is a policy that every day of the week.

Thank you!
