Dallas is 8 hours behind Nairobi
Best overlap: 4:00 PM to 6:00 PM in Nairobi is 8:00 AM to 10:00 AM in Dallas.
Book within 4:00 PM to 6:00 PM Nairobi time (8:00 AM to 10:00 AM in Dallas) and both teams will be at work. Dallas is 8 hours behind Nairobi, so common hours are scarce (about 2 hours). Lock the slot, keep it short, and follow up in writing. Seasonal note: Dallas uses daylight saving and Nairobi doesn't, so double-check the times in your own months — they can move by an hour.
