FAQ
How are age and virtual age computed?
Age subtracts one if this year's birthday hasn't passed; virtual age = age + 1, a traditional Chinese reckoning.
How is the zodiac determined?
By the Gregorian birth year mapped to the twelve Earthly Branches (does not account for the Start-of-Spring; fine for general lookup).
