I am surprised that the Factbook does not have an entry on the Exodus -- as a concept, not the book of Exodus. I can't be the only person that wanted to look this event up.
The word "Exodus" does not appear on the Timeline either, at least using this word. The events "Israelites Leave Egypt (early)" and "Israelites Leave Egypt (late)" are there, which amount to the same thing. But I suspect many people would want to filter the Timeline by Exodus to see when event this occurred.
