A world clock for real life
Multiple city clocks, one shared moment
Meridian is a free world clock on wwclock.com for comparing the current time across cities. Keep a few favorite places together, check their local dates, and see how far ahead or behind they are. No account is needed: your clock collection stays in this browser.
Use it before calling family overseas, checking in with a remote teammate, or following the day in a place you plan to visit. Analog faces help you read the time at a glance, while digital displays make hours, minutes and seconds explicit. Switch between 12-hour and 24-hour time without changing your city list.
How to compare time zones
- Add your cities. Open Add city and search by city, region or time-zone identifier. You can remove a clock and undo the change.
- Read the local time and date. All clocks represent the same moment. Check Yesterday or Tomorrow when a city is on a different calendar day from your location.
- Expand a clock. Select a card to see its full date, UTC offset and time difference from your device location. Select it again or use the collapse control to return to the compact view.
For an international team, add the cities where people actually work rather than assuming everyone in a country uses the same time zone. Some countries span several zones, and similar-looking abbreviations can refer to different places. The IANA identifier in each card makes the selected zone explicit.
World clock or timezone converter?
A world clock answers “What time is it there now?” A date-aware timezone converter answers “What time will this event be there?” Meridian handles the first question: it compares current city times and their offsets. It does not yet let you enter a future meeting date.
For a future call, confirm the event date in a calendar or date-aware converter. The difference between cities may change when daylight saving starts or ends, especially during weeks when regions change their clocks on different dates. Do not assume today's offset will apply all year.
Understand the time behind each clock
Meridian takes the current moment from your device and uses your browser's time-zone data to display local times. The IANA Time Zone Database documents the regional rules used by many operating systems and browsers. Browser updates matter when governments change those rules.
The display updates every second while the page is active. If the time looks wrong, check your device clock and browser version first. Day/night styling is a simple local-time cue, not a sunrise or sunset forecast. Read how Meridian works for the practical limitations.
A few useful answers
Does the world clock adjust for daylight saving time?
Yes. Meridian uses the time-zone rules available through your browser to calculate each city clock at the current moment. Cities can change clocks on different dates, and some do not observe daylight saving at all. Keep your browser and operating system updated so their time-zone data stays current.
Will my cities and settings be saved?
Selected cities, the light or dark theme, and the 12-hour or 24-hour format are saved in local storage in this browser when storage is available. They are not synchronized between devices. Private browsing, clearing site data or blocking storage may remove or prevent saved preferences.
