West Greenland Summer Time

Denmark, including the dependencies Faroe Islands and Greenland, uses six different time zones.

UTC+1 as standard time, and UTC+2 as daylight saving time, with transition dates according to the European Union rules.

UTC±0 as standard time, and UTC+1 as daylight saving time.

UTC±0 year around, no daylight saving time

UTC-1 as standard time, and UTC±0 as daylight saving time.

UTC-3 as standard time, and UTC-2 as daylight saving time.

UTC-4 as standard time, and UTC-3 as daylight saving time, with transition dates according to the United States rules.

All of Greenland uses daylight saving time, except for the northeast coast. The transition dates are according to the European Union rules, except for the Thule Air Base which uses United States transition dates and where the below description is not valid.

Daylight saving time starts at 01:00 UTC on the last Sunday in March and ends same time on the last Sunday in October each year, simultaneously in all affected areas.

This means that in Denmark proper, the transition is at 02:00 local standard time (03:00 daylight saving time), and in the Faroe Islands one hour earlier. In most of Greenland the transition takes place at 22:00 local standard time on the day before (23:00 daylight saving time), four hours before Copenhagen.
