The best windows to reach Denmark.

Denmark runs at +01:00
The zone is Europe/Copenhagen. Every window on this page is worked out from that offset rather than a rule of thumb, so the times shown are the ones that actually apply to Denmark.
Clocks change here
Denmark observes daylight saving, shifting to +02:00 in its summer. A window that works in January moves by an hour later in the year, so re-check before scheduling a recurring call.
