Medellín is 2 hours ahead of Vancouver
Best overlap: 8:00 AM to 4:00 PM in Vancouver is 10:00 AM to 6:00 PM in Medellín.
Keep meetings inside 8:00 AM to 4:00 PM in Vancouver — that maps to 10:00 AM to 6:00 PM in Medellín. Despite the 2-hour difference, an 8-hour overlap keeps things simple and gives both teams breathing room. Because Vancouver and Medellín don't both observe daylight saving, plan to re-check the overlap around March and November.
