World Clock

See the Time Anywhere in the World Instantly

Coordinating work across time zones is one of the most common friction points in remote teams, international business, and travel planning. You need to know whether your colleague in Tokyo is still at their desk, whether a store in London has opened yet, or what time a live event in Sydney will start in your local time. Searching “current time in city X” over and over is tedious. A dedicated world clock solves this by putting every time zone on a single screen.

This tool runs entirely in your browser. There is no account to create, no data sent to a server, and no tracking. You add the cities you care about, and each clock ticks forward in real time using your device’s system clock and the IANA time zone database for accurate offset calculations.

Why Time Zone Math Is Harder Than It Looks

Time zones are not simple fixed offsets from UTC. Many regions observe daylight saving time, shifting their clocks forward or backward at different dates depending on the country. Some zones use half-hour or even quarter-hour offsets. India is UTC+5:30, Nepal is UTC+5:45, and the Chatham Islands in New Zealand use UTC+12:45. Trying to do this math in your head, especially when DST transitions happen on different dates in different hemispheres, leads to errors.

This tool handles all of that automatically. It reads the IANA time zone database, which is maintained by a global community and updated multiple times per year to reflect legislative changes. When a country decides to abolish or adopt daylight saving time, the database is updated and your clocks stay accurate.

Practical Use Cases

Distributed engineering teams use world clocks to find overlapping hours for stand-ups and pair programming sessions. Sales teams track when prospects in target markets are in business hours before making calls. Travelers set up clocks for their origin city and destination to manage jet lag and keep appointments in both zones. Event organizers display clocks for their audience’s key regions so marketing materials show the correct local start times.

Designed for Daily Use

The tool saves your selected cities in the URL so you can bookmark your personal dashboard. Open it in a pinned browser tab and glance at it throughout the day. The minimal interface avoids clutter, showing only the information you need: city name, current time, current date, and UTC offset.
