This allows for some interesting situations. The most extreme situation: Say you are born at 11:59pm on December 31st. One minute later when it is January 1st you will be considered 2 years old.
I have to ask Koreans which year they were born to get a true sense of how old they are.
Then there is the whole Lunar calendar birthday thing, which is another can of worms.
So, happy birthday everyone???
