Time Zone Converter

Select the source time zone and enter the time. Select the target time zone and the converted time appears instantly. You can also set a specific date to account for daylight saving time changes that shift an hour forward or backward depending on the season.

Yes. The converter uses the IANA time zone database, which includes all historical and current daylight saving time (DST) rules for every region. Specify the date along with the time for accurate DST-aware conversions — this matters especially during the spring forward / fall back transition weeks.

Enter your local time and date, select your time zone as the source, then check what time it would be in each participant's time zone. Find a time that falls within business hours (typically 9 AM–6 PM) for all parties. Working hours overlap is usually a 3–4 hour window for US to Europe, and early morning for US to Asia.

UTC (Coordinated Universal Time) and GMT (Greenwich Mean Time) are very nearly identical and are interchangeable for most purposes. UTC is the modern international time standard. GMT is the historical predecessor. UTC is kept precise using atomic clocks; GMT is based on Earth's rotation. In practice, they differ by less than a second.

IST (India Standard Time) is UTC+5:30. EST (Eastern Standard Time) is UTC-5. The difference is 10 hours 30 minutes. IST is ahead of EST. For example, 5:00 PM IST = 6:30 AM EST (same day). During EDT (Eastern Daylight Time, UTC-4), the difference is 9 hours 30 minutes.

The converter supports all major IANA time zones — over 400 named zones covering every country and territory in the world, including regional US zones (ET, CT, MT, PT), European zones (CET, EET, WET), Asian zones (IST, JST, CST, SGT), and more.

Yes. Set your local time zone as the source with the current time, and select any country's time zone as the target. The converter shows the exact current time in that location. This works as a world clock for any time zone.

Yes. Select a future date in the date picker. The converter accounts for daylight saving time changes that may affect the offset on that specific future date, ensuring you get the correct time for scheduling events weeks or months in advance.
