Good to know
- Sunrise and sunset are when the top of the Sun meets a level horizon, allowing for the usual bending of light by the air. Hills, buildings and height shift what you see by a few minutes.
- Civil, nautical and astronomical twilight end when the Sun is 6°, 12° and 18° below the horizon. Golden hour here is the photographers’ usual definition: the Sun less than 6° above it.
- Worked out when the page loads from NOAA’s solar equations, for 27.8° N, 120.7° E, and accurate to about a minute.
