Best overlap: 8:00 AM to 3:00 PM in Manchester is 11:00 AM to 6:00 PM in Istanbul.
Both offices are open during 8:00 AM to 3:00 PM Manchester time, which is 11:00 AM to 6:00 PM in Istanbul. With 7 hours in common, treat scheduling almost as if the two cities were in the same region. Because only Manchester changes its clocks, the overlap above isn't fixed; expect a one-hour shift when Manchester enters or leaves daylight saving.
