Dol, the traditional way of celebrating a birthday of a one-year old child in South Korea.
East Asian age reckoning is a concept and practice that originated in China and is widely used by other cultures in East Asia. Newborns start at one year old, and at the beginning of lichun (usually February 4th, sometimes February 5th) which is the first of the 24 solar terms, one year is added to the person's age. In other words, the first year of life is counted as one instead of zero, so that a person is two years old in his or her second year, three years old in his or her third, and so on. Since age is incremented on the beginning of solar term rather than on a birthday, people may be one or two years older in Asian reckoning than in the Western system.
In China, the age changes on the first day of lichun, which is the first solar term of the 24 solar terms, which usually falls some time on 4th of February, though sometimes it falls on the 5th as well. The current age reckoning system in use in South Korea is based on the Gregorian Calendar, though originally Koreans also followed lichun as the beginning of the year and also the date for change of age.
In Eastern Outer Mongolia, age is traditionally determined based on the number of full moons since conception for girls, and the number of new moons since birth for boys.
The idea of a universal birthday disappeared from all of Sinosphere, China and Japan having switched over to the western age reckoning system, with the sole exception of Korea, though the universal birthday shifted from lichun to New Year's Day.
In either the traditional or modern age system, the word sui (traditional Chinese: 歲; simplified Chinese: 岁; pinyin: suì), meaning "years of age", is used for age counting. When a person's age is given in a publication, it is often specified whether that is his or her traditional age (traditional Chinese: 虛歲; simplified Chinese: 虚岁; pinyin: xūsuì) or modern age (traditional Chinese: 周歲; simplified Chinese: 周岁; pinyin: zhōusùi) or shisui (traditional Chinese: 實歲; simplified Chinese: 实岁; pinyin: shísùi).
When a child has survived one month of life (29 days if lunar month reckoning) a mun yuet (Chinese: 滿月; pinyin: mǎnyuè) celebration can be observed in which duck or chicken eggs dyed red are distributed to guests to signify fertility.
Japanese uses the word sai (歳 or 才) as a counter word for both the traditional and modern age system.
The traditional system of age reckoning, or kazoedoshi (数え年), was rendered obsolete by law in 1902 when Japan officially adopted the Western system, known in Japanese as man nenrei (満年齢). However, the traditional system was still commonly used, so in 1950 another law was established to encourage people to use the Western system.
Today the traditional system is mainly used by the elderly. Elsewhere its use is limited to traditional ceremonies, divinations, and obituaries.[original research?]
Koreans generally refer to their age in units called sal (살), using Korean numerals in ordinal form. Thus, a person is one sal ("han sal", 한살) during the first calendar year of life, and ten sal during the tenth calendar year.
The 100th-day anniversary of a baby is called baegil (백일), which literally means "a hundred days" in Korean, and is given a special celebration, marking the survival of what was once a period of high infant mortality. The first anniversary of birth named dol (돌) is likewise celebrated, and given even greater significance. Koreans celebrate their birthdays, even though every Korean gains one 'sal' on New Year's Day. Because the first year comes at birth and the second on the first day of the lunar New Year, a child born, for example, on December 29 (of the lunar calendar) will reach two years of age on Seollal (Korean New Year), when they are only days old in western reckoning.
In modern Korea the traditional system is most often used. The international age system is referred to as "man-nai" (만나이) in which "man" (만) means "full" or "actual", and "nai" (나이) meaning "age". For example, man yeol sal means "full ten years", or "ten years old" in English. The Korean word dol means "years elapsed", identical to the English "years old", but is only used to refer to the first few birthdays. Cheotdol or simply dol refers to the first Western-equivalent birthday, dudol refers to the second, and so on.
The Korean Birthday Celebrations by the lunar calendar is called eumnyeok saeng-il (음력 생일, 陰曆生日) and yangnyeok saeng-il (양력 생일, 陽曆生日) is the birthday by Gregorian calendar.
For official government uses, documents, and legal procedures, a chronological age system is used akin to the system used in Western countries. Regulations regarding age limits on beginning school, on alcohol and tobacco use, as well as the age of consent, are all based on a chronological system (man-nai).

^ abHilts and Kim, (2002), p.228 (quote) "Koreans have a peculiar way of calculating age. When you're born, you're already one year old, and then you get another year older when New Year's Day rolls around. The result is that your hangungnai (한국나이), 'Korean age', is usually one to tow years older than your man-nai (만 나이), 'actual age'. Under-age kids sometimes try to take some advantage of this, but eligibility for drinking, obtaining license etc is determined by your actual age."
