Regularly occurring South Korean festivals and celebrations range from religious and traditional festivals, such as Buddha’s birthday to more bizarre festivals, such as the garlic festival. For Buddha’s Birthday, a national holiday in early May, South Koreans celebrate by decorating temples and honoring Buddha at the temples, and also by attending many light festivals, such as one along Cheonggyecheon (청계천), a small stream in the center of Seoul. The two most important Korean holidays are Chuseok (추석), or Korean thanksgiving, and Seolnal (설날) or Lunar New Year. During these holidays, all shops are closed as Koreans return to their hometown to celebrate and honor their family. Family forms the nucleus of Korean society, and weddings provide a major opportunity for familial celebration with two types of weddings, traditional and modern. Some couples perform both ceremonies, while some only perform one.
