Ólavsøka or Olsok, opening of the Løgting session. (Faroe Islands and the Nordic countries)

Ólavsøka is the biggest summer festival in the Faroe Islands, and by most Faroese considered as the national holiday of the Faroes along with Flag Day on 25 April. Ólavsøka is celebrated over two days, from the 28th to the 29th of July, the second of which is the day when the Faroese Parliament (Løgting) opens its session.

Olsok is a national day of celebration on July 29 in the Nordic countries of Norway and the Faroe Islands, and also in the provinces of Härjedalen in Sweden and Savonlinna in Finland.

The Løgting is the unicameral parliament of the Faroe Islands, an autonomous territory within the Danish Realm.

The Faroe Islands are an archipelago in the North Atlantic Ocean and an autonomous territory of the Kingdom of Denmark. Located between Iceland, Norway, and the United Kingdom, the islands have a population of 54,900 as of June 2025 and a land area of 1,393 km². The official language is Faroese, which is partially mutually intelligible with Icelandic. The terrain is rugged, dominated by fjords and cliffs with sparse vegetation and few trees. As a result of its proximity to the Arctic Circle, the islands will experience perpetual civil twilight during summer nights and very short winter days; nevertheless, they experience a subpolar oceanic climate and mild temperatures year-round due to the Gulf Stream. The capital, Tórshavn, receives the fewest recorded hours of sunshine of any city in the world at only 840 per year.

The Nordic countries are a geographical and cultural region in Northern Europe, as well as the Arctic and North Atlantic oceans. It includes the sovereign states of Denmark, Finland, Iceland, Norway and Sweden; the autonomous territories of the Faroe Islands and Greenland; and the autonomous region of Åland.
