International Age vs. Korean Age

For hundreds of years, Koreans have kept track of age differently than the rest of the globe. In addition to being recognized as the Korean age, it is also known as the lunar age, nominal age, or East Asian age calculation. The Korean calendar advances a person’s age by one year on New Year’s Day rather than on their birthday. There are two reasons behind the calculation method, which account for the majority of the variance between one’s Korean age and their biological age. However, before we continue, let’s confirm that you may now use a free online age calculator to calculate age from date of birth and let yourself know how old am I.

First, in Korea, the nine months of your prenatal period are regarded as the first year of your life. The result is that a newborn’s Korean age is one. On the other hand, biological age may be determined using a free birthday calculator online and starts at zero at birth. Second, calendar years rather than the actual number of years since your birth are used to calculate your age in Korea. No matter if their birthdays have already passed in the current year or not, Koreans add one year to their seniority as soon as the New Year begins. The biological age is determined by adding one year to the actual day of birth.

You will learn a little bit about Korean age methods in this post.

Let’s begin!

The Korean Age System:

Your real age is raised by one or two years under the Korean age system. This is done in Korea because people there think that a pregnant woman’s gestational period determines the age of her unborn child (that is up to 9 months). When a baby is born in Korea, he is already one year old. In addition, many Koreans continue to use their actual age as opposed to their Korean age.
