There were plenty of volcanic eruptions in the 1600's, but not many more than in other centuries. I don't think that is the answer.

How about above normal tectonic activity, aka, earthquakes, in shaking up the planet just a teenie little bit, enough to shake it's rotation off by maybe just a degree or two.......
Think that's possible?
