About this tool

World Clock is a live, multi-city dashboard that shows the current wall-clock time in every zone you care about, all on one screen. Each card refreshes once per second from your system clock, so a glance is enough to read the seconds tick across New York, London, Dubai, Tokyo, and any other city you add. Cards report the local time (12-hour with AM and PM or 24-hour, with or without seconds), the calendar date in that zone, the GMT offset (UTC-08:00, UTC+05:30, and so on), the zone abbreviation (PST, IST, JST) when the browser exposes one, and the day shift relative to your home zone (Same day, Next day, Previous day, or a count of days). A coloured day-phase pill (Night, Early morning, Morning, Afternoon, Evening) gives an at-a-glance read on whether someone in that city is likely awake, and a separate Working hours pill lights up when the local clock falls between 09:00 and 17:59, which is exactly what you need to decide whether a video call is reasonable on the other side of the planet. Your browser zone is detected automatically and the matching city (if it is in the list) is added to the dashboard and marked Home, with a vs Home column on every other card showing how many hours ahead or behind that city sits. A search box filters the city library by city name, country, or IANA prefix (try europe/ or asia/), and one-click presets load common groups: Major hubs, US coast to coast, Europe, Asia and Pacific, Americas, and Trading floors. A copy-snapshot panel produces a plain-text report of the current state of the dashboard (with the ISO instant in the header) that you can paste into Slack, an email, or a meeting brief so everyone is looking at the same moment. Useful for distributed teams scheduling stand-ups, freelancers coordinating with international clients, travelers planning calls home, frequent flyers tracking arrival times, investors watching market opens across exchanges, and anyone who has ever asked what time is it in another city right now. Times come from the browser's built-in IANA time zone database, which applies daylight saving rules automatically and reports the correct offset across DST boundaries. Everything runs locally in the browser, so the cities you watch never leave your device.
