Christmas Eve (Christianity) and its related observances: Quviasukvik, the Inuit new year (Alaska, Canada, Greenland and Russia)

Quviasukvik, is the first day of the year according to Inuit. The festival of the New Year is celebrated by Inuit, Yupik, Aleuts, Chukchi, NunatuKavummiut and the Iñupiat. The feast originally derives from traditional Inuit religion but in modern times, it has Christian influences.

Alaska is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is considered to be the northernmost, westernmost, and easternmost state in the United States. It borders the Canadian territory of Yukon and the province of British Columbia to the east. It shares a western maritime border, in the Bering Strait, with Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south. Technically, it is a semi-exclave of the U.S., and is the largest exclave in the world.

Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, making it the world's second-largest country by total area, with the world's longest coastline. Its border with the United States is the longest international land border. The country is characterized by a wide range of both meteorologic and geological regions. With a population of over 41 million, it has widely varying population densities, with the majority residing in urban areas and large areas of the country being sparsely populated. Canada's capital is Ottawa and its three largest metropolitan areas are Toronto, Montreal, and Vancouver.

Greenland is an autonomous territory in the Kingdom of Denmark. It is by far the largest geographically of three constituent parts of the kingdom; the other two are metropolitan Denmark and the Faroe Islands. It shares a small 1.2 km border with Canada on Hans Island. Citizens of Greenland are full citizens of Denmark and of the European Union. Greenland is one of the Overseas Countries and Territories of the European Union and is part of the Council of Europe. It is the world's largest island, and lies between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Greenland's Kaffeklubben Island, off the northern coast, is the world's northernmost undisputed point of land—Cape Morris Jesup on the mainland was thought to be so until the 1960s. The capital and largest city is Nuuk. Economically, Greenland is heavily reliant on aid from Denmark, amounting to nearly half of the territory's total public revenue.
