Frequently asked questions
Does this handle daylight saving time?
Yes. Times are resolved from the IANA time zone database through your browser, so a city that is currently on summer time shows its summer offset automatically, and the switch happens on that country's own changeover date.
Why do some countries have several time zones and others none?
Time zones are a political choice, not a geographic one. China spans roughly five solar hours and runs a single official time; the United States, of similar width, runs several. Always name the city rather than the country when you schedule across borders.
