What it is

The First Day of Summer is a cherished public holiday in Iceland that signals the arrival of brighter days. Rooted in the old Icelandic calendar, which divided the year into six months of winter and six of summer, this day marks the official start of summer, even if the landscape is still frosty. For Icelanders, it is a moment to look forward to the lengthening daylight and the promise of warmth after enduring the long, dark winter. The holiday is celebrated with community gatherings, parades, and a sense of collective optimism for the season ahead.

Where it comes from

The holiday's origins lie in the traditional Icelandic calendar, which split the year into two halves: winter and summer. The First Day of Summer marks the beginning of the month of Harpa, the first summer month. Despite the often wintry weather in late April, this day has long been a symbolic turning point, representing hope and renewal. Folk beliefs added their own charm, with people placing bowls of water outside overnight—if the water froze, it was seen as a sign of a good summer to come.
