Multiple cities · One timeline
Multiple Time Zone Converter
A multiple time zone converter answers the question a two-city tool cannot: what does this moment look like for everyone at once? Add up to twelve cities, and every clock lands on the same timeline so you can read the whole picture in a single glance.

Compare many cities on one timeline
Each city gets its own row, and the columns across the top are the hours of the reference city's day. Because the columns are instants rather than wall-clock times, a vertical slice shows the same moment everywhere — and the shape of the working hours makes the pattern obvious.
When the rows are stacked like this, the overlap window appears as a visible band. If San Francisco, New York, London and Berlin are all inside 09:00–17:00 at the same time, you can see it. When there is no band, you can see that too, instead of finding out one invitation at a time.
Up to twelve cities, searchable worldwide
The converter supports up to twelve cities at once, which is comfortably more than any real meeting needs. The city list covers every country and every distinct time zone in the world, plus a searchable index of more than 30,000 cities, so "Cape Town", "Ulaanbaatar" and "Tromsø" all resolve to the right IANA zone.
Search works on city name, country name, alternative names and the raw zone identifier — type "NYC", "NYC" or "America/New_York" and you land in the same place. Press "/" or Ctrl+K anywhere on the page to open the picker.
Business hours and weekends are handled for you
Working hours (09:00–17:00 local by default) are shaded on every row, and the shared window across all selected cities is highlighted. Weekends can be toggled on with a single button, which is what you want when you are comparing a Friday afternoon with a Monday morning.
The "now" line tracks the current instant as it moves, so an open tab always shows where the day actually is rather than where it was when you loaded the page.
Share a multi-city view with one link
The URL is the state. Every selected city, the reference date, the selected hour, the display format and the weekend toggle are encoded in the query string, so copying the address bar gives someone exactly the view you are looking at.
Nothing is stored on a server and nothing is tracked. The only thing kept locally is your last set of cities, in your own browser, so the tool remembers where you usually work.
When one-by-one is enough
A multiple-city view is the right tool when the question involves a group: a stand-up, a launch window, an on-call rotation, or simply "what is happening right now across the company". For a single one-to-one conversion it is more than you need, and the two-city pages are the faster route.
The compromise most people settle on is to keep three or four cities on the timeline permanently — home, the office, and the people you talk to most — and use the planner only when a genuinely large group needs to be scheduled.
Frequently asked questions
How many cities can I compare at once?
Up to 12. Any city in the world can be added, and the picker searches more than 30,000 places by name, country, alternative name or raw IANA zone id.
Can I share a multi-city time zone view?
Yes. The share button copies a link that encodes the selected cities, the date, the hour and your display settings, so the recipient sees exactly the same view. No account is needed and nothing is stored on a server.
How do I find the working-hours overlap for several cities?
Add every city to the timeline. The shared window across all of them is highlighted automatically, and the meeting planner ranks the individual hours that fall inside it, with weekends and off-hours penalised.
Does it handle cities with 30-minute or 45-minute offsets?
Yes. India (UTC+5:30), Nepal (UTC+5:45), Eucla (UTC+8:45) and the Chatham Islands (UTC+12:45) are all computed to the minute from the IANA database.
