Born in 1970: Korean age in 2026

Someone born in 1970 is 56 in international age after their birthday in 2026 and 55 before it. In the old Korean counting age they would be 57, and their year age is 56. 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 56 (or 55 before the birthday) is the age that counts on paper. 1970 was the Year of the Dog (개띠) — though a birthday before Seollal (February 6, 1970) is sometimes counted as the Rooster, the sign of 1969.

Three ways to count the age of someone born in 1970

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.	55 before birthday, 56 after
Year age (연 나이, yeon-nai)	2026 − 1970. Same for everyone born in 1970, birthday ignored.	56
Old Korean age (세는 나이, se-neun nai)	2026 − 1970 + 1. 1 at birth, +1 every January 1.	57

Counting from November 12, 2026: a person born in 1970 whose birthday falls between January 1 and November 12 has already turned 56 this year, and one born later in the year is still 55. When fans online say "Korean age", they usually mean the old counting age (57 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 1970, 2026–2030

Year	International age before birthday	International age after birthday	Year age	Old Korean age
2026	55	56	56	57
2027	56	57	57	58
2028	57	58	58	59
2029	58	59	59	60
2030	59	60	60	61

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 (57 vs 55 in 2026), and only one year ahead after the birthday.

Korean zodiac for 1970: Dog

In the 60-year sexagenary cycle, 1970 is the Gyeongsul year (경술년), the year of the Metal Dog. Koreans call the animal sign 띠 (tti), so a person born in 1970 is "개띠". 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 1970 fell on February 6. If you were born between January 1 and the day before that, you are sometimes counted as the Year of the Rooster (1969) instead. The same animal returns every 12 years, so people born in 1958 and 1982 share the Dog sign. The next Year of the Dog is 2030.

Milestones in Korea for people born in 1970

These years add the age set by Korean law to 1970. 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	1977	Passed	For those born March–December. Under the old rule, January–February babies were eligible a year earlier (1976) and were called 빠른 년생 ("early-born"); some waited and entered in 1977.
Year age 19: may buy alcohol and tobacco	1989	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 1970 reaches this on January 1 regardless of birthday. This uses today's rule; the rule in 1989 may have been different.
Military service examination (men)	1989	Passed	Then called the conscription examination; the age rule at that time may have differed.
National Pension old-age pension starts (age 65)	2035	In 9 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 1970 in Korean age?

In 2026, the old Korean counting age (세는 나이) of someone born in 1970 is 57. Their international age, the explicit legal default in Korea since the June 28, 2023 amendments, is 55 before their birthday and 56 after it, and their year age is 56.

What is the Korean zodiac animal for 1970?

1970 is the Year of the Dog (개띠), the Gyeongsul year (경술년) in the sexagenary cycle. Seollal in 1970 was on February 6, so if you were born before that date you are sometimes counted as the Rooster 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 1970 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 1970 has a year age of 56 in 2026, so this rule no longer applies to them.
