780,000 years ago is the scientifically accepted geomagnetic reversal.
Polar shift is still debatable. It's theorized to have taken place 17,000 to 12, 000 years ago which explains the extinction of many species like the mammoth.

I believe it was somewhere around 10-12,000 years ago. It may have been even sooner. I remember when I was a kid seeing a documentary about the Great Pyramids and one of them had a shaft that pointed to a star that doesn't have much significance now, but would have been the "North" star in 2800 BC (E)

I may be off by a year or two but, I think it was about 5 billion years ago, during the ice age that froze the Earth completely.
