Solar elevation angle (for a year) Calculator

Calculates a table of changes in the solar elevation and azimuth angles for a year and draws the chart.

Input negative degree for west longtitude and south latitude.
Daylight Saving time is not taken into consideration.

    Purpose of use
    Determining at what times of year, what times of day, and in what direction it's possible to see rainbows at my location (the sun needs to be less than 42 degrees above the horizon).

    I know how to get my latitude & longitude, so could use this site, but if there were an option for typing in the nearest city, even though it'd be less precise, a lot more people would be able to use it.

    Bug report
    Relative to the diagram of the which angles are given in the table, the Azimuth and Elevation angles do not make any sense. How can the midday sun be only on a bearing (Azimuth) between 39 and 67 degrees? I could understand these angles if they are given from the East axis. Then the Azimuth would be in the region of 129 to 157 deg, i.e. approximately in the south east direction. Also, how can the sun elevation be higher in the wintertime than in the summer months? Possibly if these angles were measured from the vertical (Zeneth) axis they would make more sense. Sorry but in my mind the information given here is incorrect.

    I'm a photographer, figuring out the sun's position during certain days/months so I can take beautiful photos in a 'controlled' environment.
