Greenland National Day in Nuuk/national
Greenland's National Day, known as Ullortuneq, falls on the summer solstice each 21 June, marking both the 1985 introduction of Home Rule and 2009's move to fuller self-government, celebrated in Nuuk with flag-raising, traditional drum dances, community feasts, and open-house kaffemik gatherings under near-continuous daylight.
Greenland National Day falls on 21 June, deliberately chosen to coincide with the summer solstice, the longest day of the year, when Nuuk experiences more than 21 hours of daylight.
