Why working-hour overlap matters
Most distributed-team friction is not cultural, it is arithmetic. A team split between New York and London has only a narrow band of hours where both sides are inside a normal working day, and that band shifts twice a year when one region changes its clocks and the other does not. Planning recurring meetings against a fixed "9am for us" rule is the single most common reason someone ends up on a call at 11pm.
Every pair page on this site computes the overlap from the IANA time zone database in your own browser, so it reflects daylight saving rules in force today, not a hardcoded offset.
