This version of the Natural Frequency JavaScript Solar Position Calculator calculates solar position values for each specified time step over a given day of the year. The tabulated data is displayed in the text box at the bottom of the form, allowing you to copy/paste it to wherever you need it.

Your first step in the use of this tool is to set the Latitude and Longitude of the desired location - making sure to first set the TimeZone value as this will make entering the longitude easier. In addition to the time step Sun positions throughout the day, it also calculates Sunrise and Sunset times as well as the Declination and Equation of Time. Click the Calculate button to perform the calculation and populate the tabulated list.
