Best overlap: 11:00 AM to 6:00 PM in Karachi is 8:00 AM to 3:00 PM in Amsterdam.
Plan around 11:00 AM to 6:00 PM in Karachi, which is 8:00 AM to 3:00 PM in Amsterdam, to catch everyone during office hours. Amsterdam is 3 hours behind Karachi, but you'd hardly notice — 7 hours of shared hours makes this feel like working in neighbouring time zones. Note that Amsterdam follows daylight saving while Karachi stays put, so the times above drift by an hour seasonally.
