World Clock
World Clock shows the current time in dozens of major cities spanning every continent, updated live as you watch. Add or remove cities to build a custom multi-timezone dashboard for your team or family. Every clock follows the official IANA time zone rules for its city, including automatic daylight saving time transitions. The tool runs entirely in your browser, with nothing uploaded and no account required.
Frequently asked questions
Does World Clock account for daylight saving time?
Yes. Every clock uses the official IANA time zone rules for its city, so daylight saving time transitions in spring and fall are applied automatically without any manual adjustment.
How do I add or remove a city on World Clock?
Pick a city from the list to add its live clock to your dashboard, and remove any city you no longer need — the layout is entirely yours to customize.
What is the difference between World Clock and GMT Offset Clock?
World Clock tracks named cities and automatically adjusts for daylight saving time, while GMT Offset Clock tracks a fixed UTC offset like GMT+5:30 that never shifts for DST.
How many cities does World Clock cover?
It includes dozens of major cities spanning every continent, and you can add or remove cities freely to focus on the ones you actually track.
Is World Clock accurate for scheduling meetings across countries?
Yes — because each clock applies the real time zone rules, including daylight saving time, for its city, the displayed times are accurate for planning calls, releases, or meetings across regions.
