World Clock
See the current time in cities around the world at a glance.
What it is
A world clock shows the current time in several places at once. Zonex's world clock is a free, browser-based way to keep multiple cities on screen together — ideal for distributed teams, people with family abroad, traders following global markets, and travelers planning the next leg of a trip.
Instead of converting one time at a time, you see every city's clock side by side and read the whole world in a single glance.
How to use Zonex
Setting up a world clock takes only a few seconds:
- Open Zonex on the Time tab.
- Set a source city as your reference point.
- Add the cities you want to watch — up to seven — from the list of 40 cities built in.
- Leave the time on now so every city shows its live local time.
- Glance down the list to see who is starting their day, mid-afternoon, or already asleep.
Each layout has a shareable link, so a team can agree on one world clock view and everyone opens the same thing. When you need to pin down an exact meeting slot, switch to a specific time with the time zone converter.

Why use Zonex
Zonex's world clock is built for a quick read. The interface stays clean and uncluttered, with no ads or sign-up, and it loads instantly in any browser.
Daylight saving is applied automatically per city using the IANA time zone database, so a clock is never an hour off. It defaults to dark mode, works on phone and desktop, and is completely free, with nothing to install.
