Frequently asked questions
Does it handle daylight saving time?
Yes — the conversion uses the full time-zone rules for the specific date, so DST is applied automatically.
Why these particular cities?
They span the major business time zones. Each represents its whole zone, so nearby cities share the result.
Is the conversion done online?
No — it uses the time-zone database already built into your browser, entirely locally.
