Why does Super Junior’s Choi Siwon have 2 birthdays?

Choi Siwon has two birthdays because his birth was not registered until almost a year after he was born. This is not an uncommon practice in some countries, where parents have a certain period of time to register their child's birth. However, it's unclear why Siwon's parents waited so long to register his birth. As a result, the February 10th date was recorded as his official or registered birthday, even though his actual birthdate is April 7th. This is why he is often celebrated on both dates by his fans and colleagues.
