What Is a World Clock? See Current Time in Cities Worldwide on a Map

A world clock shows the current local time in major cities around the globe on a single map, updated in real time. Instead of manually adding or subtracting UTC offsets for each city, you can glance at the table and immediately see the local time, date, and difference from your chosen base time zone for every city listed.

Daylight saving time is handled automatically, so city pairs whose time difference shifts with the seasons — Tokyo and London, or Tokyo and New York, for example — always reflect the UTC offset that is actually in effect on that date. Beyond "Current time," the "Set a time" mode lets you anchor the whole table to any future or past date, which makes it just as useful for planning next month's meeting as for checking the time right now.

How to Use the World Clock

Choose a base mode Pick "Current time" to use the live clock, or "Set a time" to anchor the whole page to a specific date and time instead.
Set the base time zone and date (if using "Set a time") Enter the reference time zone and date/time you care about, and every city's time updates to match that exact moment.
Read the time from the map or the table The map labels and the table rows are linked, so you can check a city's time, date, and time difference from either view.
Use the day/night coloring to judge the hour at a glance Each city is shaded differently for daytime (6:00–17:59) and night (18:00–5:59), so you can tell instantly whether it's a reasonable time to call.
Check sunrise and sunset if it matters for your plan The "Sunrise" and "Sunset" columns tell you how much daylight a city has left, which is handy when the timing of daylight itself matters.

Tips for getting more out of it

City labels on the map and table rows change color between daytime (6:00–17:59) and night, so you can tell at a glance what time of day it is in another city.
For a future international meeting, use "Set a time" and select the actual meeting date. Reusing today's time difference can cause a one-hour error if daylight saving time changes before the event.
London and UTC are not the same all year. London observes GMT (UTC+0) in winter and BST (UTC+1) in summer, so it is one hour ahead of UTC during British Summer Time.
The United States and Europe change their clocks on different dates. During the gap, differences such as New York–London can temporarily be one hour shorter than usual.
When comparing the Americas with Asia or Oceania, check the previous or next calendar date as well as the clock time. Non-whole-hour offsets such as India's UTC+5:30 are handled correctly.

When the World Clock Comes in Handy

Scheduling calls and meetings across overseas offices

Line up the current time in every participant's city and pick a slot that falls within everyone's working hours, even in weeks when the time difference is temporarily thrown off by daylight saving time.

Checking local time before a trip abroad

Set the destination city's time to your travel date to see what time — and how much daylight — you'll have on arrival, which helps with jet lag planning and booking activities.

Coordinating with overseas players or viewers for games and streams

Check when your audience or opponents in another region are actually awake and active, then schedule your session or broadcast to land in that window.

Tracking trading hours for overseas stock and currency markets

See the local time in financial centers such as New York or London and translate their opening hours into your own time zone before the market moves.

Picking a considerate time to call family or friends overseas

The day/night shading on the map shows at a glance whether it's the middle of the night where they are, so you can avoid calling at an awkward hour.

World Clock Glossary

UTC (Coordinated Universal Time): The global reference time scale that never shifts for daylight saving time, kept constant all year round.
GMT (Greenwich Mean Time): Time measured at the Greenwich meridian. On today's clocks it shows the same value as UTC+0.
BST (British Summer Time): The UTC+1 time London observes in summer, one hour ahead of winter GMT.
Daylight saving time (DST): A seasonal practice of moving clocks forward by one hour to make better use of daylight. Start and end dates vary by country and region.
UTC offset: How many hours and minutes ahead of or behind UTC a location's local time runs. Some regions, such as India at UTC+5:30, use offsets that aren't whole hours.
IANA time zone name: An identifier such as "Asia/Tokyo" from the international database that maps a region to its full set of time rules, including DST history and past policy changes.
Time difference: The gap between the local times of two places. Because DST transition dates differ by region, this gap isn't always the same throughout the year.

Frequently asked questions

London uses GMT (UTC+0) in winter and British Summer Time (BST, UTC+1) in summer. During BST, London is one hour ahead while UTC itself never changes for daylight saving time.

UTC is the international reference time scale, GMT is Greenwich Mean Time, and BST is the UTC+1 time used in the UK during summer. UTC and GMT currently show the same UTC+0 clock value, but London switches to BST in summer.

Countries and regions use different daylight saving rules and transition dates. The US and Europe do not change clocks on the same dates, so their city-to-city difference can shift by one hour for several weeks.

Yes. Choose a base time zone and date in "Set a time" mode to see every city's time, date, and UTC offset at that moment. Selecting the actual event date helps prevent daylight saving mistakes.

Yes. It's applied automatically based on the IANA time zone database. If you pick a date during DST in set-a-time mode, the UTC offset switches to the value for that date.

Use our companion Time Zone Converter. It accepts IANA time zone names such as Asia/Karachi and converts dates and times between any two zones.

UTC vs GMT vs BST: Why World Time Differences Change

Coordinated Universal Time (UTC) is the international reference time scale used to coordinate standard frequencies and time signals. The International Bureau of Weights and Measures (BIPM) computes it from atomic-clock data contributed by national laboratories. UTC never switches for daylight saving time; Japan Standard Time, for example, remains UTC+9 all year.

Greenwich Mean Time (GMT) is time at the Greenwich meridian and currently shows the same clock value as UTC+0. The terms are often used interchangeably in everyday life, but UTC is an atomic international time scale, while GMT historically derives from mean solar time at Greenwich.

London uses GMT (UTC+0) in winter and British Summer Time (BST, UTC+1) in summer. A London clock being one hour ahead of UTC is therefore correct during BST. New York, Sydney, and many other cities also change their UTC offset seasonally.

A time zone is more than a fixed “UTC plus or minus” number: it is a set of regional rules covering daylight saving time and historical policy changes. Because the US and Europe change clocks on different dates, the difference between their cities can temporarily shift during the year. Always pair a city with the event date when scheduling.

Now for a little timekeeping trivia. Until the mid-19th century, each town set noon by its own local sun. Once railways expanded, travelers had to reset their watches from station to station; US railroads reportedly operated with more than 50 different company times at one point.

The turning point was the 1884 International Meridian Conference in Washington. It selected the meridian through the Greenwich Observatory as longitude zero, laying the foundation for today's global system. Japan adopted Japan Standard Time on January 1, 1888, based on the 135°E meridian near Akashi.

Even atomic time has to account for an unruly planet. Earth's rotation varies slightly, so leap seconds have been inserted to keep UTC close to astronomical time. Because those sudden extra seconds can disrupt computer systems, the international community has agreed to change the current frequent-adjustment system by 2035.
