Yes, all times are calculated using the browser's built-in timezone database, which automatically accounts for daylight saving time rules for each location.

Yes, each clock updates every second based on your device's current time, staying accurate as long as your device's clock is correctly set.
This tool displays the current, continuously updating time across any combination of world cities you choose, making it easy to see at a glance what time it is for colleagues, clients, or friends in different parts of the world.
Each clock uses the Intl.DateTimeFormat API, a standard browser feature, to format the current moment according to a specific city's timezone rules — automatically accounting for daylight saving time changes based on that location's specific rules and the current date. This means the displayed times are always accurate, even during periods when different regions have shifted their clocks for daylight saving at different times of year.
All time calculations happen directly in your browser using built-in JavaScript APIs — no data is sent to a server.
