World Clock
This world clock shows the current local time in cities around the world, updating live every second. See what time it is right now in New York, London, Tokyo, Dubai, Arizona, Hawaii, and more, each with its current UTC offset so you know how far ahead or behind it is. Pick a city to feature, or scan the full list at a glance.
Quick answer
Each clock shows the current local time for that city, updating every second.
Cities around the world
What this tells you
- •Each clock shows the current local time for that city, updating every second.
- •Daylight saving time is handled automatically, so summer and winter offsets are correct.
- •The UTC offset next to each city shows how far ahead or behind Coordinated Universal Time it is.
- •Arizona and Hawaii do not use daylight saving, so their offsets stay the same all year.
How to Use
- 1Open the tool to see live clocks for major cities.
- 2Pick a city from the list to feature it as the large clock.
- 3Read the local time and date for each city.
- 4Check the UTC offset to compare how cities line up.
How It Works
Formula
local time = current UTC instant + the city's UTC offsetEvery clock starts from the same instant in Coordinated Universal Time, then shifts by each city's current UTC offset. Time zones that observe daylight saving move their offset by an hour in summer, which the clock applies automatically from the standard time-zone rules.
Calculation note: values are processed in the order shown above, using the current input units.
Worked Examples
What time is it in Arizona when it is noon UTC?
Arizona sits at UTC-7 all year because it does not observe daylight saving, so noon UTC is 5:00 AM in Phoenix.
What time is it in Tokyo when it is noon UTC?
Tokyo is at UTC+9, so it is 9 hours ahead. Noon UTC is 9:00 PM the same day in Tokyo.
UTC Offsets for Common Cities
Standard UTC offset for each city. Daylight saving shifts some by one hour in summer.
| City | Time Zone | Standard UTC Offset |
|---|---|---|
| Los Angeles | Pacific | UTC-8 |
| Phoenix (Arizona) | Mountain (no DST) | UTC-7 |
| Chicago | Central | UTC-6 |
| New York | Eastern | UTC-5 |
| Honolulu (Hawaii) | Hawaii (no DST) | UTC-10 |
| London | GMT | UTC+0 |
| Madrid (Spain) | Central European | UTC+1 |
| Dubai | Gulf | UTC+4 |
| Mumbai (India) | India | UTC+5:30 |
| Singapore | Singapore | UTC+8 |
| Tokyo | Japan | UTC+9 |
| Sydney | Eastern Australia | UTC+10 |
Offsets shown are standard time. During daylight saving, zones that observe it move one hour later, so New York becomes UTC-4 and London becomes UTC+1.
Common mistakes
- Assuming Arizona changes with the rest of Mountain Time. Most of Arizona does not observe daylight saving, so its clock stays at UTC-7 all year.
- Forgetting daylight saving when comparing cities. The gap between two cities can change by an hour when one switches and the other does not.
- Reading the date wrong across the date line. When it is late evening in New York it is already the next day in Tokyo and Singapore.
