Useful next steps
How the overlap is found
For each day in the listing time zone, each city's working hours on its own local working days are converted to exact instants and intersected. Only time when every city is working counts. Working hours that end at or before they start run overnight.
Clock changes
A day is flagged when any city, or the listing time zone, has a different UTC offset on the day before and the day after. Shared windows can move by an hour around these dates, so check them before you book.
Limits
Time zone rules come from your browser and can differ slightly between browsers. Public holidays are not known; remove those dates yourself.
