What is Korean Age?

Korean age, or "man-nai," diverges from the standard age calculation used in many Western cultures. Instead of counting birthdays, Koreans factor in the time spent in the womb. Consequently, a newborn in Korea is considered one-year-old at birth, and everyone ages a year on the lunar new year.

Cultural Significance

Understanding Korean age is crucial for anyone engaging with Korean society, be it for travel, business, or social interactions. Respect and politeness, deeply ingrained in Korean culture, often hinge on acknowledging and addressing individuals by their Korean age.

Calculating one’s Korean age requires a multi-step process that takes into account both the lunar and solar calendars. To determine the Korean age, one must consider the year of birth and the current year, along with the occurrence of the Lunar New Year, which typically falls between January 21 and February 20.

The first step involves subtracting the birth year from the current year to obtain the person’s age in the Gregorian calendar. However, the process does not end here. To adjust for the cultural aspect of aging, individuals born before the Lunar New Year must add one year to their calculated age. On the other hand, those born after the Lunar New Year need not add an extra year.


Assuming a birth year of 1990 and the current lunar year as 2023:


Hence, the Korean age is 34.

However, if the Lunar New Year has not yet occurred, the individual would be considered 34 years old according to the Korean age system.

Demystifying the Korean Age Calculation

But how does it work? Delve into the simplicity of Korean age calculations, a far cry from the complexities of the birthday paradox calculator.

Basic Formula (Based on the Current Year)

i) If Calculating Based on Current “Western” Age

ii) If your birthday has passed: Korean age = your age + 1

iii) If your birthday has not passed: Korean age = your age + 2

Understanding the nuances is crucial; the Korean age system diverges from the Western system in two key ways. In Korea, you’re one year old at birth, counting the prenatal period as a year of life. Koreans age a year every New Year, irrespective of their birthday, setting it apart from the Western system.

Q1. How do i Calculate my Korean Age

In Korea, people use a different system to calculate age known as “Korean age” or “Man-nai” (만 나이). The Korean age is determined by adding one or two years to your international age, depending on your birthdate within the current year.

If someone is 48 years old internationally, you need to consider their birthdate within the current year. If they have celebrated their birthday, add 2 to their international age; if not, add 1. So, if someone who is 48 internationally has already celebrated their birthday in the current year, their Korean age would be 48 + 2 = 50.
