What is TimezoneCast?

TimezoneCast is a free visual time zone converter and world clock for comparing cities, finding meeting overlap, and sharing time zone plans.

How do I find the best meeting time across time zones?

Add each city, then move the time cursor until the working-hour bands overlap. That overlap is usually the best meeting window.

Can I share a time zone comparison?

Yes. Use the Share button to copy a link that encodes your selected cities, date, and time. Anyone who opens it sees exactly your setup.

Does TimezoneCast handle daylight saving time?

Yes. TimezoneCast uses IANA time zone data so daylight saving time changes are handled automatically for every city.

Is TimezoneCast free?

Yes. TimezoneCast is completely free and does not require sign-up.
