Live data providers

Time & time zones

Local times, UTC offsets and daylight-saving rules follow the IANA Time Zone Database, the same standard used by operating systems worldwide.

Weather & air quality

Current conditions, forecasts and AQI readings come from Open-Meteo, an open weather API aggregating national weather services.

Exchange rates

Currency conversion uses ExchangeRate-API; rates refresh regularly and are indicative, not transactional quotes.

Public holidays

Holiday dates are computed from each country’s own holiday law by the python-holidays library, restricted to the statutory public category, and rebuilt for each calendar year. Counts cover holidays observed across the whole country; regional and state holidays are not included. Totals are cross-checked against the independent Nager.Date dataset. Full method on methodology.

Points of interest & photography

Landmark listings and city imagery come from public geographic and photography APIs; images remain the property of their photographers.

Derived data

Cost-of-living figures, remote-work scores and comparative rankings are compiled by the TimeDateLive Editorial Team from public data and community input, and are reviewed periodically. Questions about any figure: hello@timedatelive.com.
