Timezone Converter
Convert any time between the world's IANA timezones and see multiple cities side by side. Scheduling across continents stops being a mental math exercise.
How to use the Timezone Converter
- Enter the date and time you want to convert.
- Choose the source timezone the moment belongs to.
- Pick the destination timezone or compare several at once.
- Read the converted local times for each selected zone.
When the Timezone Converter is useful
- Scheduling meetings across distributed teams.
- Checking whether a flight connection or event time works for you.
- Coordinating calls with clients or family in other countries.
- Converting webinar or stream start times into your local clock.
How the Timezone Converter works
Conversion uses the full IANA timezone database your browser carries, so daylight saving transitions are honored automatically: a 9 AM New York meeting lands at 2 PM London in summer but 2 PM shifts relative to zones that do not observe the change. Multi-city comparison shows several zones at once for scheduling sweet spots. All conversion happens locally against your device's timezone data.
Limits to keep in mind
Historical dates far in the past, or rules that changed since your browser last updated, may use the current transition rules; verify critical conversions near daylight-saving boundaries.
Frequently asked questions
Does it handle daylight saving time?
Yes, each zone's DST rules are applied automatically, including zones that skip it entirely.
What is an IANA timezone?
The standard named zone database browsers use, like America/New_York, which encodes each region's rules.
Can I compare more than two zones?
Yes, add multiple destination zones to see them side by side.
