In South Korea, New Year's Day, known locally as Seollal, is celebrated with much gusto and enthusiasm. It is one of the most significant traditional holidays in the country, usually lasting three days: the day before Korean New Year, Korean New Year itself, and the day after Korean New Year. During this period, people take time off from work, return to their hometowns and gather with family. The celebration typically involves honoring ancestors and sharing a special meal.

Food is a significant part of New Year's celebration in South Korea. A common food item associated with New Year's Day is Tteokguk, a soup with thinly sliced rice cakes, which is consumed with the belief that it grants good luck for the upcoming year. Feasting upon Tteokguk is not just a culinary delight but also symbolizes turning a year older. A traditional food preparation, Charye, meant for ancestral table settings is also quite prevalent as a mark of respect and remembrance to those who have passed away.

Cultural activities are another highlight of New Year's Day celebrations in South Korea. People partake in traditional games like Yutnori, a board game that involves throwing sticks. They also spend time in Hanbok, traditional Korean clothing, and perform Sebae, a deep formal bow of respect to their elders as part of the celebrations. It is an essential custom where children wish their elders a year of health and prosperity, in return, they receive gifts and words of wisdom. New Year's Day in South Korea brings families closer, respecting their roots and traditions while welcoming the New Year with happiness and positivity.
