I had one history prof in college who told us in the opening moments of his first class, that he didn’t really care about actual dates, and he’d never ask a date question on a test, which caused an audible sigh of relief in the room. He felt that knowing the CHRONOLOGY of events was better than the actual dates. It was one of the few insightful things I ever learned from a History professor.

Just yesterday there was a Jeopardy question about history, and I didn’t know the answer, but they gave a person’s name, and with that I was able to eliminate guesses that were after that person’s time. I didn’t know the exact dates of those eliminations, but I knew in general that they were after that person. That only left me with a few options left, and I wasn’t sure about one, so I guessed the other, and was right. It was an example of just knowing chronology was good enough.

Besides, if you need to lock down a strict fact like a date, we have a super computer in our pocket holding the entirety of human knowledge. Google it.
