Hi. I want to be able to find the hour angle at each day of the year. Wikipedia sent me on a wild goose chase of Julian Day Numbers and some useless formulas that place solar noon at the same time every day. For those who may be used to different terms, hour angle is the amount of time (in degrees) that a position on earth is away from solar noon. Ideally I would like to be able to find the hour angle, but finding solar noon will also be acceptable as well, as I can find the hour angle from that.(adsbygoogle = window.adsbygoogle || []).push({});

One site suggested that my hour angle is equal to the local sidereal time subtract the right ascension. The problem with this is I don't know how to calculate sidereal time, or right ascension. If anyone could shed some light for me(no pun intended), it would be much appreciated
