How to use it
- Your time zone is selected automatically as the starting place.
- See the current time in the other places, or pick a date and time to convert.
- Add or remove places as you like.
How to convert a time
The starting place is set to your device's time zone. By default the converter shows live times: the current time in each place, updating every second. To convert a specific moment, click into the date or time field and change it, for example "next Tuesday at 9:00 AM in New York". Every place in the list updates to show the matching local time, the date (which may be a day earlier or later), the UTC offset and the difference from your starting place.

U.S. time zones
| Time zone | Example city | Standard time | Daylight time |
|---|---|---|---|
| Eastern (ET) | New York | UTC−5 (EST) | UTC−4 (EDT) |
| Central (CT) | Chicago | UTC−6 (CST) | UTC−5 (CDT) |
| Mountain (MT) | Denver | UTC−7 (MST) | UTC−6 (MDT) |

Daylight saving time
In most of the U.S., daylight saving time starts on the second Sunday in March and ends on the first Sunday in November. Europe switches on the last Sundays of March and October, so for a few weeks each spring and fall the gap between the U.S. and Europe is one hour smaller than usual. Many countries, including Japan, China and India, don't use daylight saving time at all, and in the Southern Hemisphere it runs during our winter.
The converter uses your browser's built-in time zone database, which knows these rules for past and future dates, so you don't have to keep track.
Tips for scheduling across time zones
- Always state the time zone in invitations: "10:00 AM ET / 7:00 AM PT".
- For meetings with Europe, late morning Eastern Time is usually afternoon there.
- For Asia, early evening on the U.S. East Coast is morning in Tokyo, Seoul and Singapore.
- Watch for the date change when converting to places across the International Date Line, such as Auckland or Sydney.
All time zones
The city list covers major U.S. and world cities, and the second part of each menu lists every IANA time zone your browser supports, such as America/Boise or Asia/Kathmandu (which is UTC+5:45). The converter runs entirely in your browser. For the official U.S. time, see time.gov.
Frequently asked questions
What time is it in London when it's 9 AM in New York?
Usually 2:00 PM, because London is five hours ahead of New York. For a few weeks in spring and fall, when daylight saving schedules differ, it's 1:00 PM.
How many hours ahead is Eastern time from Pacific time?
Eastern time is 3 hours ahead of Pacific time all year.
Does Arizona observe daylight saving time?
Most of Arizona doesn't, so it stays on Mountain Standard Time (UTC−7) year-round. The Navajo Nation does observe it.
What is UTC?
Coordinated Universal Time, the reference time scale for time zones. U.S. Eastern Standard Time is UTC−5.
Does the converter handle daylight saving time automatically?
Yes. It applies the rules in effect on the date you choose, for every place in the list.
