The History of the First Day of Summer?

The holiday comes from Iceland's old Norse calendar, which divided the year into only two main seasons: winter and summer. According to this calendar, summer began in mid-April (after April 18), when daylight increased and nature began to show signs of renewal, even though temperatures were still low. The day was seen as a turning point, symbolizing hope and survival after enduring the long, dark winter.

Icelanders believed that if winter and summer "froze together" (a cold night before a mild summer day), it was a sign of a good summer ahead. Families prepared for this day with small feasts, communal gatherings, and sometimes rituals to honor the change of season.

The First Day of Summer has been recognized as a public holiday in Iceland since 1921. Over time, it evolved into a cultural celebration rather than a purely seasonal marker.

Today, it is celebrated with parades, brass bands, outdoor games and family events, organized by towns and local communities. Children often receive "summer gifts", a tradition that has parallels with Christmas gifts in the winter.

Despite often cold weather, Icelanders use the day to embrace optimism, marking the symbolic start of brighter, warmer days.
