Nairobi is 7 hours ahead of Atlanta
Best overlap: 8:00 AM to 11:00 AM in Atlanta is 3:00 PM to 6:00 PM in Nairobi.
Plan around 8:00 AM to 11:00 AM in Atlanta, which is 3:00 PM to 6:00 PM in Nairobi, to catch everyone during office hours. A 3-hour overlap gives you a workable daily window; aim for earlier in it to avoid clipping the end of someone's day. Don't be caught out by clock changes — Atlanta observes daylight saving and Nairobi doesn't, so the offset varies by an hour through the year.
