설날, or Lunar New Year, is a significant holiday in Korea that marks the beginning of the lunar calendar. It usually falls in late January or early February and is celebrated with family gatherings, traditional foods, and various customs. People often wear hanbok, a traditional Korean dress, and pay respects to their ancestors through a ritual called jesa. During 설날, families enjoy special dishes like tteokguk, a rice cake soup that symbolizes the gaining of a year in age. Children receive sebae money from elders as a token of good luck and blessings for the new year. The holiday emphasizes family bonds and cultural heritage.
