Lagos is 2 hours behind Kyiv

Best overlap: 10:00 AM to 6:00 PM in Kyiv is 8:00 AM to 4:00 PM in Lagos.

For a call that suits both sides, look at 10:00 AM to 6:00 PM in Kyiv / 8:00 AM to 4:00 PM in Lagos. Because you share 8 hours of the workday, there's no need to compromise; book the time that suits the meeting, not the map. Remember that Kyiv shifts for daylight saving and Lagos doesn't, so recalculate the overlap after each clock change.
