World Clock

About the World Clock

The MyCalendarTools World Clock shows live local times for major cities around the globe, updating every second in your browser. No server calls, no delays — just accurate time using your device's built-in timezone data, including daylight saving adjustments where your browser supports them.

Time zones divide the world into 24 regions (with many sub-zones), each offset from Coordinated Universal Time (UTC). For example, Sydney, Australia is UTC+10 in winter and UTC+11 during Daylight Saving Time, while London switches between UTC+0 (GMT) and UTC+1 (BST). The World Clock handles these transitions automatically.

Who benefits from a World Clock?

Remote teams — instantly see whether colleagues in Tokyo or Toronto are within business hours before booking a call.
Freelancers & contractors — track client time zones while managing your own schedule.
Travellers — stay connected to home time while adapting to a local clock abroad.
International event planners — find a meeting slot that works across multiple continents.
Online gamers & streamers — schedule live events across a global audience.

How to use this tool

Six popular cities load by default. Use the Add Clock button to include additional cities from the dropdown list. Each clock card shows the local time, date, and day of the week so you can tell at a glance if your contact is waking up, at lunch, or heading to bed. To remove a clock, simply refresh the page to reset to the defaults.

For a deeper dive into comparing two specific time zones, try the Time Zone Converter. To set a countdown to a future event, head to Countdowns.
