Seollal is a festival and national holiday commemorating the first day of the Korean calendar, which in turn originated from lunisolar calendar. It is one of the most important traditional Korean holidays. The celebration usually lasts three days: the day before Korean New Year, Korean New Year itself, and the day after Korean New Year. During this time, many Koreans visit family, perform ancestral rites, wear hanbok (한복), eat traditional food, and play folk games. Additionally, children often receive money from their elders after performing a formal bow.

Korean New Year 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.

Customs

The Korean New Year is typically a family holiday. The three-day holiday is used by many to return to their hometowns to visit their parents and other relatives, where they perform an ancestral ritual called charye. The three days are the day of, the day before, and the day after. Koreans not only travel within the country, but around the world, as well. Many Koreans travel from overseas to visit their families for this annual holiday. Since it is one of the few times families may be able to get together and catch up on one another's lives, it is considered respectful and important to attend the holiday. Often, the family members first visit the elders, and this includes the grandparents and the parents. It is also considered respectful for people to visit their mothers- and fathers-in-law during the Korean New Year.

Many preparations go into celebrating the Korean New Year. During the first morning, Koreans pay their respect towards their ancestors. Traditional foods are placed on a table as an offering to the ancestors, and a rite begins with deep bows from all family members. This is a sign of respect and a very important practice on the first day of the New Year in Korea. It is also where they pray for the well-being of all the family members. Many Koreans dress up in colourful traditional Korean clothing called hanbok, usually worn for special occasions such as weddings, Korean New Year, child's first birthday, amongst others. However, with modernization and evolving mores in the culture, more people tend to prefer westernized, modern clothing to the hanbok. After the rite, the members have a big feast.

Additionally, Koreans follow a zodiac similar to the Chinese zodiac. 12 animals represent the 12 years in sequential order with the rat/mouse representing the first year. Buddha is believed to have invited animals from all over the world to visit, to which only 12 visited. In return, he honoured them by naming the years in the order that they arrived. Koreans believe that specific zodiac animals bring specific resources and qualities. For example, the year 2014 was the year of the horse, and it was considered a good year in the money and career aspect of life. It is said that a person born in a specific zodiacal year will carry that zodiac animal's characteristics. As a result, Koreans plan their year and activities around it to have a good, prosperous year. Parents may have even planned the birth year of their child, so the child may have a specific characteristic. It is fair to say that the Korean zodiac is an important part of Korea's culture.

Another custom observed is the lighting of a "moon house" built from burnable firewood and branches. This symbolizes the warding off of bad/evil spirits for the new year. Many also choose to add wishes they want to come true in the next year to the moon house.

Sebae

Sebae (lit. "worship elders") is a ritual of filial piety that is traditionally observed on Seollal. Dressed in traditional clothing, people wish their elders (grandparents, parents and aunts and uncles) a happy new year by performing a deep traditional bow (rites with more than one bow involved are usually for the deceased) and saying the words 'saehae bok mani badeuseyo' (새해 복 많이 받으세요, "Please receive a lot of good fortune for the New Year".) Elders typically reward this gesture by giving children new year's money, or "pocket money" called Sebaet Don (usually in the form of crisp paper money) in silk bags made with beautiful traditional designs, as well as offering words of wisdom (dŏkdam). Historically, parents gave out rice cakes (ddeok) and fruit to their children.

New Year Food

Tteokguk (soup with sliced rice cakes) is a traditional Korean food that is customarily eaten for the New Year. According to Korean age reckoning, the Korean New Year is similar to a birthday for Koreans, and eating tteokguk is part of the birthday celebration. Once a person has finished eating their tteokguk, they are one year older.

On New Year's day, people prepare a lot of food and spend much of the day with family. The rice cake in the tteokguk looks like a coin, and many people eat a lot of rice cakes in the hopes of becoming rich in the new year.

Jeon, sometimes called buchimgae, is a traditional Korean dish especially eaten on the Korean New Year's Day. A savory pancake, it is ripped apart with chopsticks, instead of being sliced with a knife, in the belief of making it taste better.
