FAQ
Is daylight saving handled automatically?
Yes—the browser's IANA timezone database applies DST rules for the specific date you enter, which is why summer and winter differences vary.
What's the Korea–US time difference?
New York trails Seoul by 13h (14h in winter); LA by 16h (17h). US DST from March to November shrinks the gap by an hour.
What about cities not listed?
Pick a listed city in the same zone—Berlin/Rome/Madrid match Paris; Toronto matches New York.
