Timezone Converter
Convert a date and time across major world timezones simultaneously.
Scheduling a meeting across time zones, figuring out when a livestream starts in your local time, or coordinating with a remote team spread across continents all require converting one specific date and time into several others simultaneously — and daylight saving transitions mean a fixed UTC offset assumption can be wrong for part of the year in many regions.
This converter takes a single date and time and shows the equivalent moment across a wide set of major world timezones at once, using the IANA timezone database (the same standard timezone data used by browsers and operating systems), which correctly accounts for each region's current daylight saving rules rather than a static offset.
Each timezone's current UTC offset is shown alongside its converted time, since a timezone's offset can change twice a year in regions that observe daylight saving.

Frequently asked questions
Common mistakes to avoid
- Using a fixed UTC offset for a city instead of accounting for daylight saving, which is wrong for part of the year.
- Confusing a timezone abbreviation (like EST vs EDT) with the full IANA timezone name, which can cause ambiguity — this tool uses unambiguous IANA zone identifiers.
