What these numbers can—and cannot—tell you.
The live clock converts your device’s time with your browser’s IANA-based time zone data. It does not independently synchronize your clock. The solar calculations use SunCalc with representative city-center coordinates; civil sunrise and sunset are approximate horizon events, not weather forecasts.
Our date-aware calculations are more useful than treating Chatham Islands as a permanently fixed abbreviation. For calendar software, use Pacific/Chatham. For a one-off invitation, include the full date and a shared conversion link. Read the methodology and data limitations.
