Dear dialists, Does anyone know a formula for calculating the hour angle given the azimuth, declination, and latitude?
I’d like to know the time of day, throughout the year, when the sun will be positioned at a particular angle. This will allow me to determine when sunshine will stream squarely through a window on any (sunny) day. I’ve seen several formulae for calculating azimuth. I suspect that one of them could be rewritten to solve for the hour angle given the azimuth instead of the finding the azimuth using the hour angle (plus the declination and latitude). Unfortunately, I don’t have the math skills for this conversion. Thanks for any suggestions. --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
