World Clock
Live current time across Pacific, Eastern, London, Paris, Tokyo, and Sydney — updates every second.
Live current time across Pacific, Eastern, London, Paris, Tokyo, and Sydney — updates every second.
A world clock displays the current local time in several cities at once. Each city's time comes from its time zone rule: a fixed offset from Coordinated Universal Time (UTC) plus any Daylight Saving Time schedule. With live clocks side by side, there is no need to remember that Tokyo is 13 hours ahead of New York in summer and 14 hours ahead in winter, or to wonder whether London has switched to summer time yet.
Offsets between cities do not stay fixed through the year. The US changes clocks on the second Sunday in March and the first Sunday in November, Europe on the last Sundays of March and October, and Sydney runs DST during the southern summer, from early October to early April. Tokyo does not observe DST at all. As a result, the gap between Los Angeles and Sydney ranges from 17 to 19 hours depending on the season. Remote teams spread across continents, people serving international customers, travelers, and families with relatives abroad use a world clock to avoid calling at 3 AM or missing the end of someone's workday.
This world clock shows eight live clocks — Pacific, Mountain, Central, Eastern, London, Paris, Tokyo, and Sydney — with hours, minutes, seconds, and AM/PM, refreshing every second. There is nothing to enter: the times come from the browser's built-in time zone database, so DST changes apply automatically on the correct dates in each region. Accuracy depends on the device clock, which most phones and computers set automatically. To convert a specific future time, use the time zone converter; to read a raw timestamp, use the UTC converter.

The world clock above updates every second with the current local time in eight major cities across four continents. All times are pulled from your browser's built-in timezone database, which automatically accounts for Daylight Saving Time in regions that observe it.
| Region / City | Time zone | UTC offset | DST observed |
|---|---|---|---|
| Los Angeles | Pacific (PT) | UTC−8 / UTC−7 | Yes (Mar–Nov) |
| Denver | Mountain (MT) | UTC−7 / UTC−6 | Yes (Mar–Nov) |
| Chicago | Central (CT) | UTC−6 / UTC−5 | Yes (Mar–Nov) |
| New York | Eastern (ET) | UTC−5 / UTC−4 | Yes (Mar–Nov) |
| São Paulo | BRT | UTC−3 | No (2019+) |
| London | GMT / BST | UTC+0 / UTC+1 | Yes (Mar–Oct) |
| Paris / Berlin | CET / CEST | UTC+1 / UTC+2 | Yes (Mar–Oct) |
| Cairo | EET | UTC+2 | No |
| Dubai | GST | UTC+4 | No |
| Mumbai / Delhi | IST | UTC+5:30 | No |
| Bangkok | ICT | UTC+7 | No |
| Singapore / KL | SGT | UTC+8 | No |
| Tokyo / Seoul | JST / KST | UTC+9 | No |
| Sydney | AEST / AEDT | UTC+10 / UTC+11 | Yes (Oct–Apr) |
The US moves clocks forward one hour on the second Sunday in March ('spring forward') and back one hour on the first Sunday in November ('fall back'). Arizona and Hawaii do not participate.
Most European countries move clocks forward on the last Sunday in March and back on the last Sunday in October. This creates a brief window each spring and fall where the US-Europe time difference shifts by one hour.
Because the US and Europe switch DST on different dates. For about two weeks in spring, the US has already sprung forward while Europe has not — narrowing the gap by an hour. A similar shift happens in fall.
Use the live world clock above for the current time in Tokyo (JST, UTC+9). Japan does not observe Daylight Saving Time, so the offset is constant year-round.
Most of Africa, Asia, and South America do not observe DST. In the US, Arizona (except the Navajo Nation) and Hawaii do not observe DST. Japan, China, India, and most of the Middle East also stay on standard time year-round.
UTC (Coordinated Universal Time) is the world reference time. Local time is UTC plus or minus your timezone offset. New York is UTC−5 in winter (UTC−4 in summer). Tokyo is UTC+9 year-round.
Look up both cities in the world clock, compare the displayed times, and calculate the difference. Or use the Time Zone Converter tool to convert a specific time from one zone to another.
No. London observes Daylight Saving Time (called British Summer Time, BST) from late March to late October. During BST, London is at UTC+1, not UTC+0 (GMT). The world clock accounts for this automatically.
India uses Indian Standard Time (IST), which is UTC+5:30. India does not observe Daylight Saving Time and does not use multiple time zones despite its geographic span.
The International Date Line (IDL) runs roughly along the 180° meridian in the Pacific Ocean. Crossing from west to east subtracts a day; crossing east to west adds a day. This is why Sydney is ahead of Los Angeles not just by hours but sometimes by a calendar day.
It depends on the season. From roughly April to early October (New York on EDT, Sydney on standard time), 9:00 AM in New York is 11:00 PM the same day in Sydney; from November to early March (EST and Sydney daylight time), it is 1:00 AM the next day.
