Lagos is 1 hour behind Barcelona

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

For a call that suits both sides, look at 9:00 AM to 6:00 PM in Barcelona / 8:00 AM to 5:00 PM in Lagos. 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 Lagos doesn't use) shifts them by an hour twice annually.
