How to use the world clock
- Your own time is at the top, read from your device's clock and time zone, with the date and your UTC offset.
- To add a city, type in Add a city or time zone: a city (Bengaluru, Ho Chi Minh City), a country, an abbreviation such as JST or CET, or a zone name such as America/Chicago. About 480 cities are built in, and every zone your browser knows can be found by name.
- Remove a city with its ×, or press Reset to default cities.
- Choose 24-hour or 12-hour and switch Seconds on or off. Your cities and settings stay in this browser.
- To convert a future time or find a meeting slot, press Time Zone Converter: it opens with the same cities.
Reading the world clock
Each card shows the city's time as digits and on a small analogue face, ticking every second. Below it you see whether the date there is Today, Tomorrow or Yesterday compared with yours, how far the city is ahead of or behind you, and its UTC offset. The sun or moon follows a simple rule (06:00 to 18:00 local time counts as day): a hint of whether people are likely to be up, not a sunrise table.
The last line gives the next clock change, found by scanning the next 12 months of the time zone database for a change in offset, such as "Clocks go back 1 h on Sun 25 Oct". Places without daylight saving, such as Tokyo, Dubai and Mumbai, say none is due. The clocks are as accurate as your device's clock, and they pause while the tab is hidden to save power, catching up when you return.
Why some places are 30 or 45 minutes off
The Earth turns 15 degrees of longitude an hour, so most zones sit a whole number of hours from UTC. A few countries picked a meridian through their middle instead. India's time is based on 82.5° east, exactly 5 hours 30 minutes ahead of Greenwich, and Nepal has used 86.25° east, or 5 hours 45 minutes, since 1986. Lord Howe Island in Australia even moves its clocks by only 30 minutes in summer.
| Place | Standard time | Summer time in 2026 |
|---|---|---|
| Newfoundland, Canada (St. John's) | UTC−3:30 | UTC−2:30, 8 March to 1 November |
| Marquesas Islands, French Polynesia | UTC−9:30 | none |
| Iran (Tehran) | UTC+3:30 | none |
| Afghanistan (Kabul) | UTC+4:30 | none |
| India and Sri Lanka | UTC+5:30 | none |
| Nepal (Kathmandu) | UTC+5:45 | none |
| Myanmar (Yangon) | UTC+6:30 | none |
| Eucla, Western Australia (local, unofficial) | UTC+8:45 | none |
| Northern Territory, Australia (Darwin) | UTC+9:30 | none |
| South Australia (Adelaide) | UTC+9:30 | UTC+10:30, until 5 April and from 4 October |
| Lord Howe Island, Australia | UTC+10:30 | UTC+11, until 5 April and from 4 October |
| Chatham Islands, New Zealand | UTC+12:45 | UTC+13:45, until 5 April and from 27 September |
The International Date Line
The date line runs roughly along the 180° meridian through the Pacific, bending so island countries keep one date. Places just west of it are almost a full day ahead of places just east of it: Kiritimati in Kiribati (UTC+14) and Honolulu (UTC−10) show the same clock time, but Kiritimati is a day ahead, which is why the world clock labels cities Tomorrow or Yesterday. Countries have moved the line: Kiribati shifted it in 1995 so the whole country shares one date, and Samoa skipped 30 December 2011 to join the western side with Australia and New Zealand.
For timing rather than reading clocks, use the stopwatch or online timer; to count days between dates, the date calculator.
Privacy
The clocks run entirely in your browser from your device's clock and time zone; your location is not requested and nothing is sent to our server. Your cities and your 12- or 24-hour and seconds settings are kept in this browser's local storage.
Frequently asked questions
What time is it around the world right now?
The cards above show it live. Local times span 26 hours, from UTC−12 on uninhabited Baker and Howland Islands to UTC+14 in Kiribati's Line Islands, so at least two calendar dates are always in use, and for two hours each day three.
Which country has the most time zones?
France, because of its overseas territories: 12 time zones, or 13 counting Adélie Land, its claim in Antarctica. Russia has 11 across one continuous territory, and the United States uses 11 including its overseas territories.
Why is India 5 hours 30 minutes ahead of GMT?
India uses one time zone, India Standard Time, based on the 82.5° east meridian, which passes near Mirzapur in Uttar Pradesh, roughly through the middle of the country. With 15° of longitude per hour, 82.5° gives 5 hours 30 minutes. India has no daylight saving, so it is 4 hours 30 minutes ahead of London while the UK is on summer time.
Which place sees the new day first?
Kiritimati and the other Line Islands of Kiribati (UTC+14) are always first, followed by the Chatham Islands during New Zealand's summer (UTC+13:45), then Samoa, Tonga and, in summer, New Zealand (UTC+13).
Why does a city show the wrong time?
If every city is off by the same amount, your device's clock is wrong: turn on automatic date and time. If only one place is off, its government may have changed the rules after your browser's time zone data was last updated; updating the browser or system fixes it.
