What a world clock is for
A world clock shows the current local time in several places at once. Instead of converting one zone at a time, you keep a board of cities — your team, your clients, your family — all ticking live. The moment you glance at it you know whether it’s a sensible hour to call, and whether the date has already rolled over somewhere.
How the times stay accurate
Every clock is computed from your browser’s built-in IANA time-zone data, the same database your operating system trusts to keep its own clock correct. That means daylight-saving transitions and unusual offsets — India’s +05:30, Nepal’s +05:45 — are handled automatically, with no data to update on our end.
Reading each card
Each card shows the city’s live time, its full date, the UTC offset in ±HH:MM form and the zone abbreviation. A “Next day” or “Previous day” tag appears when that city’s calendar date differs from the first city on your board, so cross-midnight scheduling is never a guessing game.

Everything runs in your browser. The cities you add and the times shown never leave your device.
