World Time Meeting Planner
Pick two cities and a date to see every hour when both are inside a normal working day — one 24-hour timeline instead of offset math in your head.

How it works
Three steps, no submit button.
Type to search a bundled list of major cities, each mapped to an IANA time zone.
Offsets are resolved for that exact day, so daylight-saving changes are handled, not assumed.
The accent marks every hour both cities sit inside 08:00–18:00 local, with the full twin table below.
Built for distributed teams
Every hour of the day shown in your time and theirs, with +1 / −1 day markers when the dates differ.
Offsets come from your browser's tz database via Intl, so a skipped or repeated local hour is reported honestly.
If no shared working hour exists, the closest two-hour window is shown with a clear warning — never an empty card.
India, Adelaide and friends keep their :30 and :45 offsets instead of being rounded away.
No accounts, no cookies, no network calls: the city list and the math ship inside the page.
Berlin vs Paris reads as “all working hours overlap” rather than a nonsensical 10-hour window.
FAQ
Which hours count as the working day?
Any hour starting between 08:00 and 17:59 local, so a window can be at most ten hours long.
What happens on a daylight-saving switch day?
A local hour that never happens is shown as “—” and a local hour that happens twice is labelled as repeated, using your browser's own zone data.
My city is not in the list. Now what?
You get a “no city found” note naming the closest match, and the planner keeps using your previous city instead of silently guessing a zone.
Does this use my location or the network?
Only your device's own time zone, read locally, to pre-fill “your city”. The page works with the network switched off.
Can I plan far in advance?
Yes, though dates years ahead depend on the time-zone database shipped with your browser — the planner warns you when that matters.
