Sundial orientation The Gnomon on your sundial needs to point to True North in the Northern Hemisphere, or True South in the Southern Hemisphere.
Hit What's my Latitude ? then click your location on the map or drag pointer to re-draw (animate) the sundial with correct increments.
This will also display the Declination Angle for your selected location, to align the gnomon True North or South line.
Align the Gnomon with this Declination Angle to 'Set' the time.
Watch This Video to learn about compasses, true north and declination angles.
Drag the Latitude slider to see how the sundial markings change for different Latitudes.

Latitude Diameter


Adjust Diameter to fit your printed paper size.

Print and cut around the outer edge of the Sundial diagram. Fold the centre vertical line up, and the 2 True North or True South lines down to create a triangle (called the Gnomon) that stands vertically from the horizontal paper sundial face. Make sure the Gnomon stands vertically, at right angles to the sundial face.


Place the Sundial flat and level, with the Gnomon (triangle) pointing toward True North if you're in the Northern hemisphere, or True South for the Southern hemisphere.
Sundial orientation Use a clock or watch to adjust rotation to correct time. (Don't forget daylight time)

Cut and fold Gnomon Score paper before folding Score the paper along fold lines with a dull blade (butter knife) and ruler, then fold down from the score line, for a good straight fold.

Wrap a small piece of sticky tape around the end of the Gnomon to hold the sides together, and place a thin piece of stiff cardboard inside the fold to stiffen it.

Select Colour to draw a marble background on the Sundial face.




DON'T BREATH THE DUST If you're cutting blocks, concrete, stone or ANYTHING and there's DUST - DON'T TAKE THE RISK
Don't cut it, or cut it wet so there's NO DUST - Silicosis Sucks
And if you're cutting wet, wear a mask - theres dust in the spray mist too!

How should we spell it?
