Frequently Asked Questions
What is a world clock?
A world clock shows the current local time in multiple places at once, so you can check another city's time without calculating it yourself.
Does this world clock update in real time?
The displayed clocks refresh every second using your device's clock and the browser's time-zone database. Accuracy depends on your device clock being set correctly.
Does the world clock account for daylight saving time?
Yes. Each city's time is formatted with its IANA time zone, so the browser applies the applicable daylight saving rules for that location and date.
How can I compare the time difference between cities?
Add a city to your list. The clock displays its current time and the hour difference from your local time. The difference can change when either location enters or leaves daylight saving time.
Can I save the cities I care about?
Yes. Your selected cities are stored in local browser storage on this device. They are not synced to other devices or an account.
Is this world clock free?
Yes. It is free to use in a modern desktop or mobile browser, with no account or download required.
