San Diego is 3 hours behind Medellín
Best overlap: 11:00 AM to 6:00 PM in Medellín is 8:00 AM to 3:00 PM in San Diego.
Keep meetings inside 11:00 AM to 6:00 PM in Medellín — that maps to 8:00 AM to 3:00 PM in San Diego. San Diego is 3 hours behind Medellín, but the generous 7-hour window means both teams can meet well within their normal day. Because San Diego and Medellín don't both observe daylight saving, plan to re-check the overlap around March and November.
