World Time Zone Converter Dashboard

Add any city to your stack and the dashboard shows its live local time, date and UTC offset side by side with every other city you track.

Drag the hour slider to shift a proposed meeting time and each city recalculates instantly, so you can spot who is asleep before you send the invite.

Everything is computed locally with the browser's own time zone database, so results stay accurate through daylight saving changes with no page reloads.
