See the Time Everywhere That Matters to You

In a world where your team might span five continents and your clients could be in a dozen different cities, keeping track of local times across multiple time zones is a daily necessity. The World Clock displays the current time in as many cities and time zones as you need, all on a single screen, updating live so you always know whether it is business hours in Tokyo, lunchtime in London, or the middle of the night in New York.

Add Any City or Time Zone

The World Clock supports every IANA time zone, which means every city in the world is covered. Type a city name or a UTC offset and the tool adds it to your dashboard. You can add as many clocks as you need, from two or three for a small remote team to a dozen or more for a globally distributed organisation. Each clock shows the current time, the date, the UTC offset, and whether the location is currently observing daylight saving time.

Visual Time Comparison

Beyond showing raw clock faces, the tool provides a visual timeline strip that shows how each location day aligns with the others. You can see at a glance which hours overlap across all your selected cities, making it easy to find a meeting window that works for everyone. The overlapping business hours are highlighted in a distinct colour, instantly revealing the sweet spot for scheduling without the mental gymnastics of converting times in your head.

Daylight Saving Time Awareness

One of the most frustrating aspects of working across time zones is daylight saving time. The offset between two cities can change twice a year, and different countries switch on different dates. The World Clock handles all of this automatically using the IANA timezone database, which tracks historical and current DST transitions for every region. When clocks spring forward in New York but not in Phoenix, the tool reflects the change in real time so you are never caught off guard.

Perfect for Remote Teams

Remote team leads use the World Clock as their daily command centre. Before sending a Slack message, they glance at the dashboard to check whether a colleague is likely online. Before scheduling a standup, they identify the window where all three time zones have business hours overlap. Before setting a deployment window, they verify it falls outside peak hours for their user base primary markets. These small checks prevent miscommunication and demonstrate respect for team members in different parts of the world.

Travel Planning and Personal Use

The World Clock is not just for business. Travellers use it to track the time back home while abroad. Families with members in different countries use it to find good times for video calls. Sports fans use it to figure out when a match starts in their local time. Students studying abroad use it to coordinate with classmates and professors in their home university time zone. Any situation where you need to think in more than one time zone at once is a situation where this tool earns its place in your bookmarks.

Clean, Distraction-Free Interface

The dashboard is designed for quick glances rather than deep interaction. Each clock is a compact card showing the essentials: city name, current time in large readable digits, the date, and a subtle indicator of whether it is day or night there. The layout adapts to your screen size, fitting comfortably on a wide monitor alongside other windows or on a tablet propped up on your desk. No ads in the clock area, no clutter, just the information you need.

Runs Locally in Your Browser

The World Clock uses your device system clock and the browser built-in timezone support to calculate times. No API calls, no server dependency, and no personal data collected. Your selected cities are saved in local storage so the dashboard persists between visits. Add your cities once and the World Clock is ready every time you open it, free and private.
