Nairobi is 1 hour ahead of Barcelona

Best overlap: 8:00 AM to 5:00 PM in Barcelona is 9:00 AM to 6:00 PM in Nairobi.

Keep meetings inside 8:00 AM to 5:00 PM in Barcelona — that maps to 9:00 AM to 6:00 PM in Nairobi. Because you share 9 hours of the workday, there's no need to compromise; book the time that suits the meeting, not the map. These times hold for most of the year, but Barcelona's daylight saving (which Nairobi doesn't use) shifts them by an hour twice annually.
