Thank you all and my apologies for the very slow response. A "simple" medical problem of my wife's has turned into a very complex problem and is still taking a lot of time and energy.

No I do not dual boot with Windows but may in the near future to solve a couple of minor problems. Hopefully I will remain MS free.
Regarding the Date format I fixed it one night and forget who provided the solution but will comment that it was made much more difficult by one of the things that I think MS and Apple have right and Linux has totally messed up.
When I installed Nemo I found that I now had two file systems in parallel and both of them were named Files. If I had loaded these same two systems in Windoze or Apple they would display as Nautilus and Nemo, not Files and Files which make Windows infinitely more user friendly.
On the other side of the ledger Zorin is far faster than Windows in so many ways. The most pleasant one being that when I turn my Bluetooth headset on it connects almost instantly instead of taking minutes or outright failing.
Thank you all again.
