Seeing when your world is awake
Timezone maths is easy to do and easy to do wrong. Zonely puts everyone on one timeline so you read the answer instead of calculating it.
Scheduling across timezones is arithmetic anyone can do and almost everyone occasionally gets wrong. Not because subtraction is hard — because the inputs move. Daylight saving shifts on different dates in different hemispheres. India is half an hour off the grid. Someone changes city and does not mention it.
The failure is rarely a wrong number. It is a meeting that lands at 6:30am for one person and nobody notices until they join looking like they were asleep, because they were.
One timeline, not five clocks
Zonely puts every city you care about on a single horizontal timeline in your browser’s side panel. Drag across it and every row moves together. You are not converting anything; you are looking for the vertical slice where nobody’s row is dark.
It lives in the side panel rather than a popup deliberately. A popup closes the moment you click back into your calendar, which is precisely when you need it. The side panel stays open beside the thing you are scheduling.
The weather, and the one request
Zonely can show weather for each city. That is the only feature in any of our products that contacts a server: coordinates go to Open-Meteo, a free, keyless service, and come back as a forecast.
It is off by default, it is named in the privacy policy rather than softened into “may use third-party services”, and switching it off means the request is not made.
One deliberate non-feature: Open-Meteo has no severe-weather alerts endpoint. Zonely’s weather warnings are a client-side heuristic and are labelled as one. Calling them official alerts would be a safety claim we cannot stand behind, and someone would eventually rely on it.
Zonely is free on the Chrome Web Store.
