Cultural Perspectives on Age
East Asian Age Reckoning
In South Korea, China, Japan, and other East Asian countries, a person is considered to be one year old at birth, and everyone gets one year older on New Year's Day, not on their birthday.
- A baby born on December 31st would be considered 2 years old the next day
- This system is called "sui" in Chinese and "sal" in Korean
- Can make a person up to 2 years older than Western age calculation
