Our Rigorous Editorial & Algorithmic Standards

🌐

IANA tzdb Continuous Sync

Every time zone boundary and DST transition table is compiled directly from the official Paul Eggert IANA Time Zone Database (tzdb). Release candidates are regression-tested within 24 hours of publication.

☀️

Jean Meeus Numerical Verification

All solar and lunar calculations utilize rigorous ephemeris formulas from Jean Meeus' Astronomical Algorithms, cross-verified against NOAA Solar Calculators and US Naval Observatory benchmarks.

🔒

100% Client-Side Privacy

We do not operate servers that log user queries or geographic lookups. Calculations are executed exclusively on your local CPU via browser-native JavaScript and Web Workers.

♿

WCAG 2.2 AA Accessibility

Every interface is engineered to adhere to strict contrast, semantic ARIA attributes, full keyboard operability, and screen reader announcements.

Corrections & Scientific Review Policy

Precision is paramount in chronometry. If you discover an upcoming legislative time zone change or have an algorithmic suggestion, please contact our metrology editorial desk at [email protected] or visit our Contact Desk. Verified submissions are reviewed and deployed within 48 hours.
