Crayfish parties are generally held during August, a tradition that started because crayfish harvesting in Sweden was, for most of the 20th century, legally limited to late summer. Today, the kräftpremiär date in early August has no legal significance. Dining is traditionally outdoors, but in practice the party is often driven indoors by bad weather or aggressive mosquitoes. Customary party accessories are comical paper hats, paper tablecloths, paper lanterns (often depicting the Man in the Moon), and bibs. A rowdy atmosphere prevails amid noisy eating and traditional drinking songs (snapsvisa). The alcohol consumption is often high, especially when compared to the amount of food actually eaten. It is considered customary to suck the juice out of the crayfish before shelling it.
