you're already one year old when you are born, and adds another year every January 1st. So even a baby born in December 2000 would be considered 2 years old in January 2001 (although people mostly just count by months when children are that young). Jonghyun has been 25 years old in Korea since January 1st 2014 even when he was just 23 before his birthday, and the birthday in this year is considered his 25th birthday.
