Is each hour on a sundial 15 degrees?

Question

Also does anyone know does a sundial have to have the angle of lattitude on the front of the gnonom and the back or just the front?

Answer 1

360/24=15 so YES

Answer 2

No.  To be accurate, the sundial must be calibrated for your latitude, and possibly be seasonally adjusted as well.

A sundial at the north pole would have 24 hour-indicators 15 degrees apart, but it would stop working once a year for six months.

Answer 3

If there are 24 hours on a sundial, yes.

15 x 24 = 360

and 360 is a complete circle.

Answer 4

Well, the answer above is correct, but since a sundial only is effective for about 12 hours (more or less), and the sun only is seen through an arc of about 180 degrees (more or less), it's

180 degrees/12 hours = 15 degrees/hour

Same answer, just.... a little more accurate.
