RE: Killing Time With Recreational Math - Calculate Sunrise and Sunset Times Using Python
Worked perfectly for me! Btw the most accurate predictions are from JPL Horizons.

Thx for trying it out and thx for the tip. I will take a look at the JPL web site.
I couldn't get the exact times in Guide 9.1 or JPL, maybe refraction or could be the definition of sunset/sunrise. Is it the point the sun is completely below or completely above horizon, or is it when the sun's center is on the horizon. Either way great work on this!
I tried it out as well. There is a 15 minute difference between JPL and this cwlculation. I looked at JPL's parameter and they say it is for a vacuum so no diffraction effects are accounted for. I think this is the source of the differences.
