Medellín is 6 hours behind Prague
Best overlap: 2:00 PM to 6:00 PM in Prague is 8:00 AM to 12:00 PM in Medellín.
Your window to reach both cities is 2:00 PM to 6:00 PM in Prague, which converts to 8:00 AM to 12:00 PM in Medellín. Roughly 4 hours of shared hours means scheduling takes a little care — 2:00 PM in Prague / 8:00 AM in Medellín is a safe default. One seasonal catch: Prague springs forward and falls back, but Medellín doesn't, so the gap changes by an hour for several months of the year.
