MotionShine01 / Zones
Every time zone
All the time zones your browser knows, from Honolulu to Kiritimati, found by city name.
Free tool
Time zone converter, one time, every city.
Pick a date and time in one place and see it everywhere else at once: New York, London, Dhaka, Tokyo or any city you add. Daylight saving is handled for the date you pick. Each place shows whether it falls in working hours, and a 24-hour strip per city makes it easy to spot a meeting time that works for everyone. Copy all the times in one go for an invite.
The strip under each city shows 12 hours either side of the chosen time: green is 9 to 5 there, dark is night. "Use" sets the time from that city.
Time zones come from your browser's own list (the IANA time zone database), so daylight saving rules are current for the date you pick.
Your list of cities is kept in this browser. Nothing is sent.
How it works
Pick a moment, see it everywhere.
02 / Daylight saving
For the chosen date
Clocks that change in spring and autumn are handled for the exact date and time you pick.
03 / Meetings
A strip per city
Working hours in green and night in dark make the overlap easy to see.
Questions
Good to know.
Does it handle daylight saving time?
Yes. It uses your browser's time zone database and applies each place's rules for the date you choose.
My city is not in the list. What now?
Time zones are named after a big city. Add the nearest big city in the same time zone, for example Los Angeles for San Francisco.
Can I find a good meeting time?
Yes: look for the column where every strip is green, or move the time until it is.
Is my list saved?
Yes, in this browser, so your cities are there next time.
