Age is not just a number!

In most countries, your age is calculated as your 'international age,' which is determined by the number of years since you were born and starts at zero. However, some countries, like South Korea, follow a different system. If you ask South Koreans about their age, most will answer with their "Korean age," which can be one or even two years older than their international age. This system, rooted in China, considers babies as one year old on the day they're born and adds a year on every January 1.

To add more complexity, some people in South Korea use their "calendar age," which combines elements of both systems. Under this approach, babies are considered zero years old on their birthday and gain a year in age every January 1.

For instance, if you were like my youngest son and born on December 31, 2009, according to international age, you are 13 years old. However, based on calendar age, you are 14 years old, and according to Korean age, you are 15 years old.

Depending on where you live, age is clearly more than a number.
