World clock
See what time it is in the cities you care about, with the difference from your own time. Then pick a day and a time and find out when everyone is awake and at work.
Your list has no cities
Search for a city to see its time, or go back to the starting list.
Add a city
Search by city or country. A time zone name such as America/Indiana/Indianapolis also works.

Meeting planner
Pick a day and a time in one city and see what time it is in the others. The bars below show the whole day in the base city, so you can spot where everyone overlaps.
| City | Time | Day bar |

- Work hours: 9 AM to 6 PM
- Reasonable: 7 AM to 9 AM and 6 PM to 10 PM
- Night: 10 PM to 7 AM
How the time is calculated
The time is calculated from your device’s clock and your browser’s time zone rules. If your device’s clock is wrong, every city will be off by the same amount. If a country changed its rules recently, an out-of-date browser may show the wrong time.
Many places do not change their clocks during the year. Arizona, Hawaii, and India, for example, keep the same time all year.
Your time zone
How to use it
- Check the starting cities: each card shows its time, its date, and how many hours it is ahead of or behind you.
- Search for another city or country in the search box and add it. Reorder the list with the arrows or by dragging.
- In the meeting planner, choose a base city, a day, and a time, and see the equivalent time in every city over a 24-hour bar.
- Look for where everyone overlaps, copy the result as text for your invitation, or share a link with the same list.
Frequently asked questions
Where does the time on the clock come from?
It is calculated from your device’s clock and the time zone rules built into your browser, without asking any server. That is why it keeps working offline once the page has loaded. If your device’s clock is wrong, every city will be off by the same amount.
Does it adjust for daylight saving time automatically?
Yes. Each city follows the rules of its own time zone, so it changes by itself on the right day. Each card shows whether the city is on daylight saving time and the date of the next change. If a country changed its rules recently, an out-of-date browser may show the wrong time.
Why doesn’t Arizona change its clocks?
Arizona (apart from the Navajo Nation) stays on UTC−7 all year and does not use daylight saving time, and neither do Hawaii and most US territories. That is why Phoenix is on the same time as Denver in winter but on the same time as Los Angeles in summer.
How do I find a good time for a meeting across several countries?
In the planner, each city has a bar for its day: dark blue is work hours (9 AM to 6 PM), light blue is reasonable (7 AM to 9 AM and 6 PM to 10 PM), and striped is night. The “Everyone overlaps” row marks the stretches where nobody is outside reasonable hours. Click the bar or use the slider to try different times.
Where is my list of cities saved?
Only in your browser, in the site’s own storage. There are no accounts and no servers. If you clear the site data or switch browsers, you go back to the starting list. To take your list somewhere else, copy the share link.
Can I add a city that is not on the list?
The list has more than 300 capitals and large cities. If yours is missing, type the name of its time zone in the search box, for example America/Indiana/Indianapolis, and it is added with the correct time.
What a time zone is
The Earth is divided into time zones, measured as an offset from UTC, Coordinated Universal Time. New York is on UTC−5 in winter and UTC−4 in summer, London is on UTC+0 or UTC+1, and Tokyo is on UTC+9. The difference between two cities is the difference between their offsets: Tokyo and India are always 3½ hours apart, because neither one changes its clocks.
Daylight saving time
Many countries move their clocks forward an hour in the warmer months to get more daylight in the evening. The United States and Canada switch on the second Sunday in March and the first Sunday in November, Europe on the last Sunday in March and the last Sunday in October, and the southern hemisphere on the opposite dates. Because the dates differ, the gap between New York and London shrinks from 5 hours to 4 for a few weeks every spring and fall. Arizona, Hawaii, Japan, India, and most of Asia and Africa do not change their clocks at all.
An example: a meeting across three cities
A team is spread over New York, London, and Mumbai. When it is 10:00 AM in New York, it is 3:00 PM in London and 8:30 PM in Mumbai (7:30 PM while New York is on daylight saving time). A time that looks perfect for two of the cities leaves the third one in the evening or the middle of the night. The planner stacks the three 24-hour bars on top of each other, and the “Everyone overlaps” row marks the stretches where nobody is outside reasonable hours.
How to use the planner
- Choose the base city, the day, and the time you want to meet.
- See what time it will be in each city and whether it is work hours, reasonable, or night there.
- Look for the stretches in the “Everyone overlaps” row where nobody is outside reasonable hours.
- Copy the text for your invitation: it lists the time in each city and flags when the date changes.
When it comes in handy
- Calls with family abroad: avoid ringing someone in the middle of the night.
- Remote work: agree on overlap hours with your team.
- Online events: announce the start time in your audience’s cities.
- Travel: work out when you land and how many hours your body clock will be off.
Tips
For recurring meetings, check the daylight saving dates in each country: the same time can shift by an hour for a few weeks. Add your teammates’ cities to the list and share the link so everyone sees the same information. If you also need a countdown or a stopwatch, try the timer and the stopwatch, or work out the hours between two times with the hours calculator.
