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 40.2° S, 71.4° W, and accurate to about a minute.
