Sunrise calculator

I thought this is a good idea.
All you need is a compass at nigh or during the day and you
can "predict" where the sun will rise in the morning

Oh dear, is that the time?

I'm off

Calculate the sunrise and sunset at any time of year in the Northern hemisphere

The chart shows the position of the sunrise and sunset for the first day of each month. Simply point the N to north and read off the direction. For dates other than the first of the month, simply gauge how far through the month you are and go between the first of the month you are in and the next month, so the 15th is about halfway.

You could print/engrave one onto a polished metal plate to make a Heliograph/signalling mirror?
