Choose a date and time, choose the time zone it is in, and see the matching local time in every zone on your list. Add any city or IANA time zone, such as America/New_York, Europe/London, Asia/Kolkata or Australia/Sydney, and remove the ones you do not need. Your list is remembered in this browser.
Daylight saving time is applied automatically for the date you pick, using the time zone rules built into your browser. Each row shows the UTC offset and marks when the time falls on the previous or next day, which makes planning international meetings much easier.

UTC, GMT and daylight saving time
UTC (Coordinated Universal Time) is the world's reference time; every time zone is written as an offset from it, such as UTC−5 for New York in winter or UTC+5:30 for India. GMT is the same as UTC for everyday use.
Many countries move their clocks forward one hour in summer. The dates differ: the USA and Canada change on different weekends from Europe, and countries in the southern hemisphere change in the opposite season. Because of this, the time difference between two cities can change during the year, which is why the converter uses the exact date.
Frequently asked questions
Does it handle daylight saving time?
Yes. The browser's built-in time zone database applies the correct rules for the date you choose, including past and future changes it knows about.
How do I find a city that is not listed?
Time zones are named after a major city in the same zone. Search for your country's capital or largest city, for example Asia/Phnom_Penh or America/Chicago. Any city in the same zone, such as Asia/Bangkok for Phnom Penh (both UTC+7), gives the same time.
What does +1 day mean?
It means the converted time falls on the next calendar day in that zone. −1 day means the previous day.
What is the difference between EST and EDT?
EST is Eastern Standard Time (UTC−5) in winter; EDT is Eastern Daylight Time (UTC−4) in summer. Choosing America/New_York applies the right one automatically.
