You could build a small script that pulls the sunrise/sunset times for your destination, then calculates the sun’s elevation angle for each hour. When the angle drops to roughly 6 to 15 degrees above the horizon, that’s the classic golden‑hour window. Feed that into a weather API to flag cloud cover and humidity—those are the real variables that mess up your perfect math. In practice, a few lines of Python with the Astral library and the OpenWeatherMap API will give you a daily window and a warning if the sky is too grey. But remember, the algorithm can only do so much; sometimes you just have to step out and see if the light feels right.

Sounds good, just remember the data’s only a guide—if the sky looks wrong, the math will still be wrong, too. Happy hunting!
