SunsetSunrise.org is a focused solar-time website built around a simple idea: give the answer quickly, then make the deeper astronomy available without burying the visitor in it.
What the Site Covers
- Sunrise and sunset
- Civil, nautical and astronomical twilight
- Day length and seasonal change
- Solar noon, altitude and azimuth
- Golden hour and blue hour
- Monthly calendars and location-based planning
- Current weather shown separately from the astronomical calculation
Editorial Approach
Pages are written around distinct user questions rather than keyword variations. Closely related phrases belong on the same useful page. The site avoids padding pages with repeated definitions simply to make them longer.
Accuracy and Limits
The goal is transparent, reproducible planning data. Where an event depends on a convention—such as golden hour—the convention is stated. Where observation can differ because of terrain or atmosphere, that limitation is stated too.
