Hi Dan,
Another, free solution would be to use www.esrl.noaa.gov/gmd/grad/solcalc/.
After giving in latitude, date and time, it provides solar azimut and
altitude (= elevation).
I have used it t
Dan,
the program AlmSun by Rafał Tomasik can compute the instant when the sun
reaches the desired azimuth and height.
More info can be found at http://almsun.pl/en/
Actually it is not freeware but it requires a small payment (it was 19 $
two years ago).
Ciao.

I don't know any software, but my approach would be:
1. Use Altitude and Azimuth and Latitude to calculate Declination
(straightforwad Spherical Trig calculation. If you need formula, it will
take me a moment to come up with it)
2. Calculate dates for the declination (longitude/time zone will
Dear all, given the azimuth and altitude of a point in the sky, what would
be the best way of finding the dates and times during which the Sun reaches
that point? Is there any software for this?
