Sankthansaften, or Midsummer's Eve, is celebrated in several countries, particularly in Scandinavia. It occurs on the evening of June 23rd, the eve of the feast day of Saint John the Baptist. The holiday marks the summer solstice, the longest day of the year, and is associated with various traditions, including bonfires, singing, and dancing. During Sankthansaften, people often gather with family and friends to enjoy outdoor festivities. Bonfires are lit to ward off evil spirits and celebrate the light of summer. In some regions, it is also customary to pick flowers and create wreaths, symbolizing fertility and the beauty of nature.
