Warsaw 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 Warsaw.
Plan around 9:00 AM to 6:00 PM in Nairobi, which is 8:00 AM to 5:00 PM in Warsaw, to catch everyone during office hours. This is one of the easier pairings: 9 hours of shared time means flexible, low-stress scheduling. Note that Warsaw follows daylight saving while Nairobi stays put, so the times above drift by an hour seasonally.
