Set your sundial on June 15. Place it so the shadow falls on the 12. Add an hour to the time if your area is on Daylight Savings Time.

    Set my sundial when? It appears in your statement like it doesn’t matter what time of the day June 15 to move the gnomon’s shadow to 12. That doesn’t make sense. I was always taught to set a sundial at noon on June 21 the longest day of the year. Why the 15th?
