Age reckoning in South Korea (and other east Asian countries) is quite different than what you might expect. Age 1 in this context could be up to 3; if year 1 is your birth date and you age up at the new year, you could be "2 years old" while being alive for only 3 days. It could also work the other way around if they follow one of the other methods. Pretty interesting and not yet fully standardized!https://en.wikipedia.org/wiki/East_Asian_age_reckoning
