A world clock and time zone converter shows the current time in major cities, converts any date and time between time zones, and finds meeting hours that work across cities. Everything runs in your browser using its built-in time zone data — no install, no signup — and daylight saving changes are applied automatically.

FAQ
Does it handle daylight saving time?
Yes. Your browser’s built-in IANA time zone database applies daylight saving rules automatically, including past and future changes shipped with your browser.
How accurate are the conversions?
Conversions use the IANA time zone database built into your browser through Intl.DateTimeFormat. Nothing is sent to a server; results are as current as your browser’s time zone data.
How does the meeting overlap finder work?
Pick two to four cities. Each row shows that city’s local hour across a 24-hour day in UTC; work hours (9:00–18:00) are highlighted, and hours inside every selected city’s work hours are marked as the best meeting window.
