World Clock
View current times in cities around the world.
How to use the world clock
Click the add-city button and start typing a city name — the search supports hundreds of major cities worldwide, keyed by their IANA time zone. Pick up to six cities and they will appear as a row of live clock cards, each updating every second. Drag cards to reorder them so your most important time zones appear first. When you are happy with the layout, hit Share to copy a URL that other people can open to see the same set of cities.
The world clock is especially useful for remote teams, international travel planning, live streams, global customer support shifts, and keeping in touch with family across continents. Because the clocks tick live rather than being a static snapshot, you can leave the tab open on a spare monitor and glance at it throughout the day.
Understanding time zones and DST
A time zone is a region that follows a uniform offset from UTC. Most offsets are whole hours (UTC-5 for US Eastern Standard Time, UTC+9 for Japan Standard Time), but some regions use half-hour or quarter-hour offsets — India is UTC+5:30, Nepal is UTC+5:45, and parts of Australia use UTC+9:30. A handful of regions also shift twice a year for daylight saving time, which is why a New York clock and a Phoenix clock can read the same time in winter but be an hour apart in summer.
The tool resolves all of this automatically using the IANA time zone database — the same source used by operating systems and programming languages. That means historical DST changes, offset revisions, and newly created zones are handled correctly without you needing to think about them.
