Accra is 2 hours behind Warsaw
Best overlap: 10:00 AM to 6:00 PM in Warsaw is 8:00 AM to 4:00 PM in Accra.
Plan around 10:00 AM to 6:00 PM in Warsaw, which is 8:00 AM to 4:00 PM in Accra, to catch everyone during office hours. Accra is 2 hours behind Warsaw, but you'd hardly notice — 8 hours of shared hours makes this feel like working in neighbouring time zones. Don't be caught out by clock changes — Warsaw observes daylight saving and Accra doesn't, so the offset varies by an hour through the year.
