Free online world clock — local time and time zones in your browser
This page is a free online world clock. It shows your local time as a large digital clock, then lets you add other cities so you can compare time zones without installing an app. Use it when you need to know what time it is now in another place, or when you want a clean fullscreen clock on a laptop or second monitor.
Each city uses a named IANA time zone, so daylight saving changes follow that zone’s rules instead of a fixed offset. Open a city page from the popular-city links if you want a dedicated clock for that location. The main World Clock page is the dashboard: several cities at once, plus a shareable URL for this view.
A world clock is not a countdown. It tells you the current time; it does not run down to a date. If you need days until a holiday or event, use the date countdown. If you need a kitchen or meeting duration that rings at zero, use the online timer.
Keep this tab open (or pin it) while you rely on the clock. Putting the laptop to sleep pauses the page like any other browser tab. Fullscreen hides chrome so the digits stay readable across a room.
Quick uses: checking a meeting time in another country, putting a clock on a TV, comparing two cities before you call, or leaving a second-monitor clock running during the workday. Add, reorder, or rename cities from the tiles below.
Plan meetings across time zones
The fastest way to find a fair meeting slot is to add both cities to this page and read the offsets side by side. A nine-hour gap means a 9 AM call for one side lands at 6 PM for the other — often the only overlap that works for a weekly call. For recurring meetings, rotate who takes the awkward hour instead of freezing the same slot forever.
Watch out for half-hour and quarter-hour offsets. India runs UTC+5:30, Nepal UTC+5:45, and parts of Australia UTC+9:30, so one zone over is not always a whole hour. Adding the exact city to this clock beats doing offset math in your head.
Share the view: once your cities are arranged, copy the page URL — the selection is encoded in the link, so a teammate opens the same dashboard instead of rebuilding it. For focus blocks with a hard stop, pair the clock with the Pomodoro timer.
Daylight saving time, handled for you
Time zones are not fixed all year. Most of North America and Europe shifts between standard time and daylight saving time, and the southern hemisphere does the opposite: London and Sydney are 11 hours apart in January but only 9 in July.
The European Union switches on the last Sunday of March and October; North America switches on the second Sunday of March and the first Sunday of November. Some large regions skip the change entirely — China and India run a single offset all year — and equatorial countries rarely use daylight saving because day length barely changes.
You do not need to track any of this. Every city here is tied to its IANA time zone (Europe/London, America/New_York, Australia/Sydney), so the displayed time updates itself on switching days. Each city page also shows its zone's standard and daylight offsets.

Frequently asked questions
- What is this online world clock?
- It is a free browser clock that shows local time and other cities’ time zones. You do not need to download an app or create an account.
- How do time zones work on this page?
- Each city is tied to an IANA time zone (for example America/New_York). The clock follows that zone’s current offset, including daylight saving, instead of a single fixed UTC offset.
- Can I use this as a fullscreen desktop clock?
- Yes. Use the toolbar fullscreen control for a large digital clock on a laptop, TV, or classroom display.
- How is a world clock different from a date countdown?
- A world clock shows the time of day in one or more cities. A date countdown counts remaining days to a holiday or event. Use this page for “what time is it there?”; use countdown for “how many days until…?”
- Do I need to keep the tab open?
- Yes. The clock runs in this browser tab. Keep the tab open and avoid putting the device to sleep if you need the display to stay live.
- Can I share my city selection?
- Yes. Arrange your cities, then copy the page URL — the selection travels with the link, so whoever opens it sees the same clock dashboard you do.
- Which regions use half-hour time zones?
- India (UTC+5:30), Iran (UTC+3:30), Afghanistan (UTC+4:30), Myanmar (UTC+6:30), and Newfoundland in Canada (UTC−3:30) are the best-known cases. Nepal is unusual at UTC+5:45.
- What is UTC?
- UTC (Coordinated Universal Time) is the reference every time zone is defined against, written as offsets such as UTC+8 or UTC−5. It never shifts for daylight saving, which is why local offsets change while UTC stays still.
- Why does the time gap between two cities change during the year?
- Because the two zones may switch daylight saving on different dates — or not at all. The London–New York gap is 5 hours most of the year but 4 for a few weeks in spring and autumn, when only one region has switched.
