Which country has the greatest number of daylight hours?

the north pole

Several countries (or rather: parts of countries) have daylight 24 hours a day around midsummer. It will have to be countries situated north of the Arctic circle, as there are no "countries" situated south of the Antarcic circle. The countries include USA (North Alaska), North Canada, most of Greenland, parts of Norway, Sweden and Finland plus Northern Russia.

You see the countries here. The Arctic circle just misses Iceland. The Arctic circle misses mainland Iceland, but hits the small island of Grimsey, with 100 inhabitants. You might not call it a "country", but Svalbard is the populated area with the greatest number of daylight hours

Quote:
There are no permanent human settlements south of the Antarctic Circle, so the countries and territories whose populations experience it are limited to the ones crossed by the Arctic Circle, i.e. Canada, United States of America (Alaska), Denmark (Greenland), Norway, Sweden, Finland, Russia, and extremities of Iceland. A quarter of Finland's territory lies north of the Arctic Circle and at the country's northernmost point the sun does not set for 73 days during summer. In Svalbard, Norway, the northernmost inhabited region of Europe, there is no sunset from approximately 19 April to 23 August.

You might argue that the US has the greatest number of daylight hours, in that during the summertime, the time which separates the sunrise in northern Maine and the moment at which it sets over the Alleutian Islands is separated by more than it takes in any other country in the world (with the possible exception of Russia).

For the countries above the Artic circle that do experience very long periods of constant daylight that is also countered with very long periods of constant night.

With Russia being the largest nation in the world it would experience the most amount of daylight hours.

But if ones talking average daylight hours wouldn't the fact that these countries have mininmal daylight during winter months mean that they migt not be the highest in total (counting daylight hours per year that is)?

In that scenario it might be the countries on the equator that get the most per year. No reference just a thought on the questions interpretation itself

If the sun were to be above the horizon 50% of the time for a standard year consisting of 8,760 hours, apparent maximal daytime duration would be 4,380 hours. However, there are physical and astronomical effects which change that picture. Namely, atmospheric refraction allows the Sun to be still visible even when it physically sets below the horizon line. For that reason, average daytime (disregarding cloud effects) is longest in polar areas, where the apparent Sun spends the most time around the horizon. Places on the Arctic Circle have the longest total annual daytime of 4,647 hours, while the North Pole receives 4,575. Because of elliptic nature of the Earth's orbit, the Southern Hemisphere is not symmetrical: Antarctic Circle at 4,530 hours receives 5 days less of sunshine than its antipodes. The Equator has the total daytime of 4,422 hours per year.[
