Closest City from the center of every Timezone

## 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
