Madrid is 1 hour behind Nairobi
Best overlap: 9:00 AM to 6:00 PM in Nairobi is 8:00 AM to 5:00 PM in Madrid.
Keep meetings inside 9:00 AM to 6:00 PM in Nairobi — that maps to 8:00 AM to 5:00 PM in Madrid. Madrid is 1 hour behind Nairobi, but the generous 9-hour window means both teams can meet well within their normal day. Keep an eye on the calendar — Madrid observes daylight saving and Nairobi doesn't, which nudges this window by an hour twice a year.
