World Clock

See the current local time in major cities around the world at a glance, with a live animated clock face for each one. Drag a clock to reorder it, click a city's name to search and swap in a different one, or use the "+" card to add more — up to 8 at once. Useful for scheduling a call across time zones, checking whether it's a reasonable hour to message someone abroad, or just satisfying curiosity about what time it is somewhere else.

How it works

Each city's time is calculated using your browser's built-in timezone database (the same one used by your operating system), which correctly accounts for daylight saving time changes and historical timezone rules — not a fixed UTC offset, which would silently drift wrong twice a year in places that observe daylight saving time. The analog clock hands are redrawn every second directly from that calculated time.

Worked example

When it's 9:00 AM in New York, it's already 2:00 PM in London, 3:00 PM in Paris, and 10:00 PM the same day in Tokyo — the exact gap changes slightly across the year as different regions shift in and out of daylight saving time.
