Set your Sundial

The best time and day to set your sundial for most accurate reading for the summer is on June 15th at 12:00. The next date that you will be able to set your sundial for accurate reading will be September 1st at 12:00.

To Set your Sundial
  • Make sure the spot that your sundial is in is level and has full sun.
  • The shadow arm (gnomon) needs to be pointed toward celestial north if you are in the northern hemisphere. This is different than the magnetic north that a compass will show you. To find celestial north you will need to set your sundial at noon. Turn the sundial so the gnomon's shadow falls directly on the sundial's mark that shows where noon is.
  • This is known as SUN TIME.
For the most accurate sundial set it on one of the following days:
April 15, June 15, September 1, December 24.

Keep in mind that to your sundial noon is always going to be when the sun is highest in the sky.
