About SunTimes
SunTimes exists to publish city-level daylight pages that are genuinely useful on their own. The goal is not to mirror a public API. The goal is to turn solar data into a planning resource that helps people make decisions.
Methodology
SunTimes calculates sunrise, sunset, twilight, and solar-noon values using astronomical formulas derived from NOAA-style solar-position methods. We render the pages on the server and refresh them on a timed revalidation cycle so the published HTML contains the useful content, not just a JavaScript shell.
Editorial standard
A city page only earns its place if it adds context beyond a single answer box. Every page is expected to carry current solar data, short-term and medium-term trend tables, a seasonal comparison, useful internal links, and text written to support specific use cases such as photography, solar planning, commuting, or travel scheduling.
What we publish
The current catalog focuses on major cities with strong search demand and clear user intent. We expand coverage gradually, keeping internal linking and content quality consistent rather than publishing large batches of empty location pages.
