that's a neat formular but HOW accurate is it exactly? For an example, you mentioned all those factors in the end (tiltangle, orbitshape etc.) and I mean, the time difference between a sunrise in June compared to one in December is several houres (at least in central europe where I live). For my purposes, I don't need the exact moment down to the minute, +/- 10 to 20 min would be accurate enough. can I acheave this with this formular?
Very interesting and clear explanation! How would one go about correcting the sunrrise/sunset times to account for Earth's tilt?

Use actual solar time
@Tettzz what do you mean?
