In Iceland, the First Day of Summer is a public holiday Rooted in the old Norse calendar, which divided the year into just two seasons, summer and winter, it marks the symbolic start of warmer days, even if the weather is still chilly. Traditionally, people would welcome the new season with parades, brass bands, family gatherings and games. Children often receive small summer gifts, and the day reflects Icelanders' resilience and optimism, celebrating brighter days ahead after the long winter.
