I would also put the Black Widow post-credit's scene between Endgame and Wandavision due to the amount of green in Ohio. I'm located PA and the green usually disappears by this time of year. So I'd imagine this scene is late Oct./Early Nov.
You seem a bit argumentative. I get we are all passionate about this technical stuff that 99.9% of the population couldn't care less about, but can you reel it back a bit? You are coming across a bit too aggressive.
They must exist in either the past, present or future. Time literally doesn't stop for anyone. It's simpler to assume the TVA scenes are set in Oct. 2023 until further data dis-proves this. Occam's razor my friend!
