So when does the sun set?

  • Where is the earth around the sun?
  • What's the angle of the earth? (Solar Declination Angle) (Latitude Based)
  • Eccentricity of the Earth's orbit (True Solar Time)
  • What time is it? (Longitude / Solar Hour)

And finally:

Solve for Solar Zenith Angle (Angle between Sun and a Pole) = 90 degrees
