For the record, I am not new to FANDOM, but this is the first (and most likely only) post I have made on the DC wiki. Recently I have been trying to get my head around all the different timelines and eras in the DC universes since the beginning in 1934, but the best explanation I could really find is this Reddit post.
However, this doesn't really delve into any of the stuff to do with the films or shows, and I would like to know more about the timelines and continuities.
