Fallout: Did the Bombs Fall on 23 October 2077?Fiction
In-universe lore. Claims are judged against the fiction's own canon, not the real world.
Ask any wastelander and they will tell you the bombs fell on Saturday, 23 October 2077. They are right - but that exact date appears nowhere in the 1997 original. It was minted for a fan-facing design document whose own author later declared it non-canon, then promoted to gospel by Bethesda.
