World Time Lab shows live day and night across the planet. Sun positions are computed with standard NOAA solar equations, and local times come from your browser's own IANA time zone database, so every calculation on this site runs on your device. Pages also load analytics from Google, which makes its own network requests. The privacy and cookie pages set out exactly what that involves.
