How does one calculate the legal age of someone born on leap day?
If someone is born on leap day, how is their birthday calculated for legal reasons on non-leap years? For example, is their 21’s birthday calculated on the 28th of February or the 1st of March. I can think of dozens of weird and unlikely scenarios where this could actually make a difference.
