When Does Aot Take Place

Where does attack on titan take place? Attack on titan takes place in 845 ce, and there has been some debate as to the exact location of the events. When and where does attack on titan take place? Anime spoilers i have done my research, and the answer is divided between ww1 and ww2, taking place in germany (paradis) and israel. It starts in 845, then jumps to 850, then to 851 and then to 854.

Their technology seems to be around 1800s for paradis and 1920s for the outside.
