How this is calculated
The difference is the gap between the two cities’ UTC offsets at a given instant, taken from the IANA time zone database via the Intl API. It is recomputed live for the current moment, and for the year’s schedule below it is evaluated across every clock change in either city — which is why some pairs have several values a year and others one.
The overlap grid uses September 3, 2026 and 9-to-5 working hours; open the meeting planner for any other date or hours.
