Korea's three-day New Year holiday, around the first day of the first month (February 9) by Korea's time: ancestral rites (charye), bowing to elders (sebae) and tteokguk. Seollal (Korean: 설날) is a Korean traditional festival and national holiday commemorating the first day of the Korean lunisolar calendar. It is one of the most important traditional holidays for ethnic Koreans, being celebrated in both North Korea and South Korea as well as Korean diaspora all around the world. Seol, written as "설" in Middle Korean in Hangul, means "year of age" since it is also the date when Koreans grow a year older, though in South Korea this has changed as of 2023. The modern Korean word for "age" – sal is derived from the same origin as seol. Nal (날) means day in Korean, derived from Old Korean *NAl. The Hanja term won-il (元日) is used, when referring to the date of the lunar new year of the Korean calendar itself. The Korean lunisolar calendar, like most other East Asian calendars such as those of Japan, Mongolia, Vietnam, among others, are all derived from historical variants of Chinese ones such as the Shixian calendar of the Ming dynasty. China and Japan use different terms for their respective new years, such as 正月 or 元日, which are derived from Classical Chinese. During this time, many Koreans would visit their family, perform ancestral rites, wear the hanbok (한복; 韓服) / Chosŏn-ot (조선옷; 朝鮮옷), eat traditional food and play traditional folk games. One of the most well known practices in the current day is receiving money from their elders after performing a formal bow, a tradition likely adopted from Confucian customs. Seollal generally occurs in January or February on the second new moon after the winter solstice, unless there is an intercalary eleventh or twelfth month in the lead-up to the New Year. In such a case, the New Year falls on the third new moon after the solstice. Wiki link Dates computed on the Chinese calendar from the Sun and Moon, in each country's own time.
