Medellín is 6 hours behind Copenhagen
Best overlap: 2:00 PM to 6:00 PM in Copenhagen is 8:00 AM to 12:00 PM in Medellín.
Copenhagen and Medellín overlap from 2:00 PM to 6:00 PM (Copenhagen) to the equivalent 8:00 AM to 12:00 PM in Medellín — that's your meeting window. Roughly 4 hours of shared hours means scheduling takes a little care — 2:00 PM in Copenhagen / 8:00 AM in Medellín is a safe default. Note the seasonal wrinkle: when Copenhagen is on daylight saving and Medellín isn't, the gap between them grows or shrinks by an hour.
