Accurate time, straight from your device
The clock above is calculated in your browser from your device clock and the official IANA time zone rules, the same database used by Android, iOS, macOS, Windows and Linux. That means it automatically follows daylight saving time (summer time) changes in every country, even when governments change the rules.
If the time looks wrong, the most common cause is that your device clock or time zone setting is off. Turning on automatic date and time in your system settings usually fixes it, because your phone or computer will then sync with an internet time server.
Why time zones exist
Because the Earth rotates 15 degrees every hour, noon arrives at different moments in different places. In the 19th century, railways and telegraphs made local solar time impractical, so countries adopted standard time zones measured as offsets from Greenwich. Today the reference is Coordinated Universal Time (UTC), and offsets range from UTC−12 to UTC+14, including zones with 30- and 45-minute offsets such as India (UTC+5:30) and Nepal (UTC+5:45).
What you can do here
Compare cities side by side with the world clock, plan a call across continents with the time zone converter, count down to an event, time a workout with the stopwatch or timer, or use the browser alarm clock. Every tool runs locally in your browser, needs no account and works on phones, tablets and desktops.
Frequently asked questions
Is the time on PlanetClocks accurate?
The displayed time comes from your device clock combined with the IANA time zone rules built into your browser. If your device syncs automatically with a network time server, it is normally accurate to well under a second.
Does PlanetClocks adjust for daylight saving time?
Yes. Daylight saving (summer time) start and end dates are applied automatically for every city and time zone, using the rules published in the IANA tz database.
What is UTC?
Coordinated Universal Time (UTC) is the global time standard. Local times are expressed as offsets from UTC, for example UTC−5 for New York in winter or UTC+9 for Tokyo all year.
Do I need to install anything?
No. All clocks and tools run in your web browser. Settings such as your world clock list are stored only on your device.
