Can someone give me a step by step Guide how to use JPL DE431 or DE441 as a Beginner.

I tried the Horizons website app and Webgeocalc but it didn't showed understandable Information. This websites forum and others were searched.

It would be enough when I'm able to read one example like:

Julian Day Number________Date__________Planet_________Position

-652942.5000000_____-6500-05-05_______Venus________aphelion

This would be very helpful.

Have you explored Skyfield library ? I used it to find solar eclipses at a particular location from 5000 BC to 2000 AD. Here is the code for your reference. https://github.com/godbolerr/indianskyfield/blob/master/iastronomy/KuruSolarEclipseBC.py
