About the World Clock
This world clock shows the local time in cities around the world right next to your own time zone, which your browser detects automatically. It is handy for scheduling calls with colleagues abroad, catching a live game or market open in another country, or checking whether it is a good time to call family overseas.
Times are calculated with the IANA time zone database built into your browser, so the start and end of daylight saving time in the US, Europe and Australia are always applied. Use the time zone converter to pick a date and time in one city and see the matching local time everywhere on your list.
How to use
- The first row is your own time. Each city below shows its local time, date and how far ahead or behind you it is; cities on daylight saving time are marked DST.
- Pick a city under Add city to add it, and remove any city with the × button.
- In the time zone converter, choose a base city, date and time to see the local time in every city on your list.
- Switch between the 12-hour and 24-hour format at the top.
UTC offsets of major cities
| City | Standard time | Daylight saving time |
|---|---|---|
| New York, Washington, D.C. | UTC−5 (EST) | UTC−4 (EDT), March–November |
| Chicago, Dallas | UTC−6 (CST) | UTC−5 (CDT) |
| Denver | UTC−7 (MST) | UTC−6 (MDT) |
| Phoenix | UTC−7 | No DST |
| Los Angeles, Seattle | UTC−8 (PST) | UTC−7 (PDT) |
| Honolulu | UTC−10 | No DST |
| London | UTC+0 (GMT) | UTC+1 (BST), March–October |
| Paris, Berlin, Rome, Madrid | UTC+1 (CET) | UTC+2 (CEST) |
| Dubai | UTC+4 | No DST |
| New Delhi | UTC+5:30 | No DST |
| Beijing, Singapore | UTC+8 | No DST |
| Tokyo, Seoul | UTC+9 | No DST |
| Sydney | UTC+10 (AEST) | UTC+11 (AEDT), October–April |
Arizona (except the Navajo Nation) and Hawaii do not observe daylight saving time, so their offset stays the same all year.
When do the clocks change?
- United States and Canada: DST starts at 2:00 a.m. on the second Sunday in March and ends at 2:00 a.m. on the first Sunday in November.
- UK and EU: from the last Sunday in March to the last Sunday in October, switching at 01:00 UTC everywhere at once.
- Southeast Australia and New Zealand: the other way round, from October (New Zealand: last Sunday in September) to the first Sunday in April.
Because the US and Europe switch on different dates, the gap between them is one hour smaller than usual for a few weeks in March and in late October/early November. Double-check meetings in those weeks with the converter.
FAQ
How does the world clock know my time zone?
Your browser reports the time zone set on your device (for example America/New_York). The first row uses it, and all differences are shown relative to it.
Are the times accurate?
They are calculated from your device’s clock. If your device clock is wrong, every city is off by the same amount, so keep automatic time enabled.
What happens if I enter a time that is skipped when DST starts?
On the day clocks spring forward, times like 2:30 a.m. don’t exist. The converter shows a warning and uses the time one hour later.
My city isn’t in the list. What should I do?
Pick a nearby city in the same time zone. For example, Milan uses Rome time, Houston uses Chicago/Dallas time, and Montreal uses Toronto time.
