Time Zone Converter

What is it?

A time zone converter is a tool that translates a specific date and time from one time zone to its equivalent in one or more other time zones. With over 400 named time zones in use across the world — and complex rules around Daylight Saving Time (DST) that differ by country and even by region — converting times accurately by hand is surprisingly difficult. This free online time zone converter handles all of that automatically. Simply pick a source time zone, enter a time and date, and add as many destination time zones as you need. The tool instantly shows the equivalent local time in every selected zone, correctly accounting for UTC offsets and any active Daylight Saving Time adjustments. It covers all IANA time zones (the international standard used by computers and servers), so you can convert between cities like New York, London, Tokyo, Sydney, Mumbai and hundreds more. The tool is especially useful for scheduling international meetings, coordinating remote teams across continents, planning travel, setting deadlines for global launches, and communicating with friends and family who live in different countries.

How to use it

1. Select your source time zone from the dropdown (or use "My current time zone" to detect yours automatically).
2. Enter the date and time you want to convert.
3. Add one or more destination time zones using the "Add time zone" button.
4. The converted times update instantly for all selected zones.
5. Click the copy icon next to any result to copy the converted time to your clipboard.
6. Toggle "Show UTC offset" to also display the raw UTC+/− offset for each zone.

Why use this tool

Scheduling across time zones is one of the most common sources of confusion in modern remote work and international collaboration. A "3 PM meeting" means very different things to someone in Los Angeles and someone in Berlin — and the gap shifts by an hour during Daylight Saving Time transitions, creating even more confusion. This converter removes the guesswork entirely. You get instant, accurate conversions that respect DST rules, so you will never accidentally schedule a meeting at 3 AM for a colleague or miss an international deadline because of a time zone mix-up. Unlike basic UTC offset charts, this tool always reflects the actual current or future offset for any given date — which is critical because many countries shift their clocks seasonally. Everything runs in your browser with no data sent to external servers. No sign-up is required, and the tool is free to use as many times as you like.
