Greenland uses Coordinated Universal Time (UTC), with a range of UTC +0 to -4. This means that if it is 18:00 UTC (6 p.m.) in Nuuk when you travel to Greenland, it would be 16:00 (4 p.m.) in New York City, USA, 21:00 (9 p.m.) in London, U.K. and 09:00 (9 a.m.) the next morning in the Antarctic South Pole.
