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. This build loads no advertising, no analytics, and no third-party scripts at all, and asks for no account. It never asks where you are unless you press "Use my location" on an eclipse page, and that reading stays in your browser. The privacy page explains what that does and does not cover.
