About this project

World Time & Weather shows the exact local time and current weather for 400 cities in 199 countries, in English, Spanish and Arabic. It is an independent project — no corporation behind it, no accounts, no tracking.

Where the data comes from

Nothing on this site is invented here, and every source is one you can check yourself:

Time is computed from the IANA Time Zone Database — the same tzdata that operating systems and programming languages use. Daylight-saving transitions come from it automatically, so when a country shifts its clocks, every page here follows the same day.
Weather comes from Open-Meteo, an open-source aggregator of national meteorological services (DWD, NOAA, ECMWF and others). Current conditions on city pages refresh continuously.
Maps are © OpenStreetMap contributors.
City facts — population, currency, languages, travel notes — are compiled from public reference sources and reviewed by hand.

What this site is honest about

Short-term weather here is an observation, not our own forecast — we do not run a forecasting model, and the same figures are available from the underlying services. What this site adds is the time-zone layer (exact local time, UTC offsets, daylight-saving behaviour), the combination of both in one place, and tools built on top: the embeddable widget and the free JSON API.

Long-range figures shown on city pages are climate averages computed from daily observations of recent years — useful for planning a trip, not a forecast for a specific day.

Free tools

Website widget — a live clock and weather card for any site, two lines of code, no signup.
JSON API — time, UTC offsets, DST behaviour and current weather for 400 cities as plain static files. No key, no rate limit.
Desktop widget — for Windows, Android and iOS home screens.

Both the widget and the API are free for commercial use. We ask for a visible link back to this site — it is how new people find the project and the entire business model of keeping them free. A rel="nofollow" link is absolutely fine.

Privacy

City pages request weather directly from Open-Meteo in your browser; nothing about you is stored on our side. There are no accounts and no advertising profiles. Details: privacy policy.

Found an error?

If a time zone, an offset or a city fact looks wrong, it matters to us — write to 50439al@gmail.com and it will be checked against the primary sources above and fixed. The same address works for questions about the widget and the API.
