Is it possible to get the angle of the Sun to a block in Minecraft?
Minecraft has shadows in some of the shaders, and the shadows are obviously created via the positon of the sun or by timing. So is there a way to actually get this angle of elevation from the ground of specific coordinates to the sun? Or, is it possible to get the shadow length of a block?
If you are talking about shaders as in shadermod/Iris/OptiFine shaders, those talk to the OpenGL graphics library directly and get the angle from their respective mod like https://github.com/IrisShaders/ShaderDoc/blob/master/uniforms.md#sun-angle from the Iris mod. There is currently no direct way to fetch the sun's angle with a command in the vanilla game.
