IANA time zone data
Location pages are tied to IANA timezone identifiers, and daylight-saving behavior follows the timezone data available in the runtime used by the site and modern browsers.
Editorial methodology
This page explains where the site’s clock, timezone, weather, solar, and holiday information comes from, how those layers are combined, and where the main limits still are.
Location pages are tied to IANA timezone identifiers, and daylight-saving behavior follows the timezone data available in the runtime used by the site and modern browsers.
Country, region, and city routes are built from structured geographic datasets and normalized slugs so users can move cleanly between country, state, and city levels.
Weather context is fetched from Open-Meteo. Solar summaries use Open-Meteo where needed and coordinate-based day calculations to describe sunrise, sunset, and daylight context.
Calendar pages and next-holiday callouts use a normalized holiday layer that prefers HolidayFinder data and falls back to date-holidays where direct coverage is missing.
| Layer | Primary source | How it is used |
|---|---|---|
| Current time and offset | IANA timezone identifiers in runtime/browser time data | Live clocks, UTC offsets, DST-aware date and time rendering |
| Weather | Open-Meteo current conditions | Temperature, apparent temperature, wind, humidity, and scene context |
| Sunrise and sunset | Open-Meteo plus coordinate-based calculations | Daily sunrise, sunset, solar noon, and day-length context |
| Holiday and celebration data | HolidayFinder with date-holidays fallback | Calendar pages, dated celebrations, and next-holiday callouts |
| Location routing | Structured world geographic datasets | Country, state, and city route generation and interlinking |
Clock values refresh live in the browser, while cached HTML pages are regenerated and reviewed when route logic, timezone handling, trust pages, or editorial sections change. The methodology and publisher pages are reviewed manually so the site’s behavior is explainable, not just functional.
Holiday coverage is country-dependent. Some years or countries have rich public and celebration datasets, while others only have partial public-holiday coverage. When coverage is thin, the site keeps the calendar itself accurate while treating the holiday layer as a best-effort structured reference.
