Born in 1999: Korean age in 2026

Someone born in 1999 is 27 in international age after their birthday in 2026 and 26 before it. In the old Korean counting age they would be 28, and their year age is 27. Korean law has long counted age in full years, and amendments effective June 28, 2023 made international age the explicit default in civil and administrative matters, so 27 (or 26 before the birthday) is the age that counts on paper. 1999 was the Year of the Rabbit (토끼띠) — though a birthday before Seollal (February 16, 1999) is sometimes counted as the Tiger, the sign of 1998.

Three ways to count the age of someone born in 1999

Method	How it is counted	Age in 2026
International age (만 나이, man-nai)	0 at birth, +1 on each birthday. The explicit legal default since the June 28, 2023 amendments.	26 before birthday, 27 after
Year age (연 나이, yeon-nai)	2026 − 1999. Same for everyone born in 1999, birthday ignored.	27
Old Korean age (세는 나이, se-neun nai)	2026 − 1999 + 1. 1 at birth, +1 every January 1.	28

Counting from November 12, 2026: a person born in 1999 whose birthday falls between January 1 and November 12 has already turned 27 this year, and one born later in the year is still 26. When fans online say "Korean age", they usually mean the old counting age (28 here), which runs one or two years ahead of international age. For an exact answer on a specific date, enter the full birth date in the international age calculator.

Age of someone born in 1999, 2026–2030

Year	International age before birthday	International age after birthday	Year age	Old Korean age
2026	26	27	27	28
2027	27	28	28	29
2028	28	29	29	30
2029	29	30	30	31
2030	30	31	31	32

The old Korean age and year age go up together on January 1, while international age goes up on the birthday itself. That is why, between New Year and the birthday, the old Korean age is two years ahead of international age (28 vs 26 in 2026), and only one year ahead after the birthday.

Korean zodiac for 1999: Rabbit

In the 60-year sexagenary cycle, 1999 is the Gimyo year (기묘년), the year of the Earth Rabbit. Koreans call the animal sign 띠 (tti), so a person born in 1999 is "토끼띠". The date on which the animal changes is not set by law; it is usually taken to be Seollal (설날), the lunar new year, while saju fortune-telling uses Ipchun (입춘) around February 4.

Seollal in 1999 fell on February 16. If you were born between January 1 and the day before that, you are sometimes counted as the Year of the Tiger (1998) instead. The same animal returns every 12 years, so people born in 1987 and 2011 share the Rabbit sign. The next Year of the Rabbit is 2035.

Milestones in Korea for people born in 1999

These years add the age set by Korean law to 1999. Early or delayed school entry, repeating a year or personal circumstances can change the real year, and where a system did not exist yet, the note says so.

Milestone	Year	As of 2026	Note
Elementary school entry	2006	Passed	For those born March–December. Under the old rule, January–February babies were eligible a year earlier (2005) and were called 빠른 년생 ("early-born"); some waited and entered in 2006.
Year age 19: may buy alcohol and tobacco	2018	Passed	Under the current Youth Protection Act (청소년 보호법) rule, a person is a minor while "current year − birth year" is under 19, so everyone born in 1999 reaches this on January 1 regardless of birthday. This uses today's rule; the rule in 2018 may have been different.
Military service examination (men)	2018	Passed	In the year of turning 19 in year age (for some, the year of turning 20).
National Pension old-age pension starts (age 65)	2064	In 38 years	The starting age depends on birth year (60 to 65). At least 10 years of contributions are required.

How Korean law counts age, and which rules still use year age, is explained on the Korean age by birth year page.

Frequently asked questions

How old is someone born in 1999 in Korean age?

In 2026, the old Korean counting age (세는 나이) of someone born in 1999 is 28. Their international age, the explicit legal default in Korea since the June 28, 2023 amendments, is 26 before their birthday and 27 after it, and their year age is 27.

What is the Korean zodiac animal for 1999?

1999 is the Year of the Rabbit (토끼띠), the Gimyo year (기묘년) in the sexagenary cycle. Seollal in 1999 was on February 16, so if you were born before that date you are sometimes counted as the Tiger instead.

Is Korean age still used in Korea?

Not officially. Korean law has long counted age in full years, and amendments effective June 28, 2023 made international age the explicit default in civil and administrative matters unless a law says otherwise. Some laws still use year age (current year − birth year), such as the Youth Protection Act for alcohol and tobacco and the Military Service Act, and the old counting age survives only in casual conversation.

When can someone born in 1999 buy alcohol in Korea?

Under the current Youth Protection Act rule, a person is a minor while "current year − birth year" is under 19. Someone born in 1999 has a year age of 27 in 2026, so this rule no longer applies to them.
