Remote and distributed work means scheduling across time zones, and that is where the ChrysoKit Timezone Converter pays off. Compare any number of cities side by side and find the overlap that works.
Why use it
Most timezone tools handle one pair at a time. Real meetings have three, four or five participants in different cities. This tool was built for that.
How to use the Timezone Converter
- Pick a source city and time.
- Add as many destination cities as you need.
- Slide the time selector to find an hour that works everywhere.
- Copy a shareable summary for the calendar invite.
Features worth knowing
Multi-city comparison
Stack as many cities as your meeting actually has.
Daylight saving aware
Automatic handling of DST transitions, including the half-hour offsets.
Shareable summary
Copy a clean text block of the time across all cities.
Pro tips
- Anchor the meeting to a city, not to your local time. It removes one round of mental conversion for everyone else.
- When pasting times into invites, include the time zone abbreviation. 'Tuesday 3pm' is ambiguous; 'Tuesday 3pm CET' is not.
- Daylight saving days are the worst day to schedule cross-country calls. Push to the day after.
Privacy first. The Timezone Converter runs entirely in your browser. Nothing you enter is sent to a server.
The Timezone Converter is the calmer way to schedule across borders. Use it before sending the invite.

Scheduling a three-continent call: a worked example
The task: find a weekly slot for participants in Athens, New York and Sydney. Walking through it properly illustrates every trap the converter exists to manage.
Start by writing all three cities against a single reference. Athens at 16:00 is 09:00 in New York and midnight in Sydney... already a failure for Australia. Slide earlier: Athens 10:00 is 03:00 New York. The viable band is brutally narrow: Athens 15:00-17:00 puts New York at 08:00-10:00 and Sydney at 22:00-24:00 (rough, but the only overlap of anyone's plausible hours). The honest output of the exercise is not a perfect slot... none exists... but a visible map of who pays the inconvenience, which can then rotate quarterly instead of permanently landing on the same office.
Then the traps. The chosen "Athens 16:00" must be pinned to one named zone, because the three regions change daylight saving on different dates... in the transition weeks of March/April and October/November, the same wall-clock meeting silently moves an hour for somebody. Sydney's offset runs opposite-season to Europe's, so the Athens-Sydney gap breathes between 7 and 9 hours across the year. And the calendar invite, created correctly with zone-aware times, handles all of this automatically... which is the final lesson: convert to choose the slot, then let the calendar own it. Humans memorising offsets is how Tuesday's call gets missed twice a year.
