Weltzeit-Dashboard

How the dashboard works

Every clock on this page is computed from a single UTC reference — your device’s clock — converted into each city’s IANA time zone. That means all cards tick in lockstep, daylight saving time is applied automatically per city, and the day/night indicator and date line show at a glance which cities are already on tomorrow’s date (or still on yesterday’s).

Your selection is stored only in your browser. To hand the same set of clocks to a colleague, use the share button: it creates a link that rebuilds the board from the URL.
