Why the gap between cities changes
Each place keeps a standard offset from UTC, and many shift their clocks by an hour for daylight saving. Because countries change on different dates, the gap between two cities is not fixed. The United States moves its clocks on the second Sunday of March and the first Sunday of November, the European Union on the last Sunday of March and the last Sunday of October, and Sydney from the first Sunday of October to the first Sunday of April.
So for a few weeks each spring and autumn, New York and London are four hours apart instead of five. This tool uses your browser’s time zone database, so it applies the right offset for the exact date you pick. The table shows the usual offsets for the cities it lists.

Planning a meeting across zones
Set the time in your own zone first, then scan the list for a slot that falls inside normal working hours everywhere. If no slot works for everyone, rotate the inconvenient hour between teams instead of always asking the same people to join early or late.
Write the zone next to the time in invitations, for example 15:00 London time, and check the date as well as the hour: a late evening in Los Angeles is already the next day in Tokyo and Sydney.
