Determining State Move Dates in a multi-step relocation

I moved from Hawaii to North Carolina this year for the new job.  Our move was as follows:

- My first day at a new Job was November 27th (at which point my employer started deducting both NC and HI state taxes)

- My first day physically in North Carolina was November 30th

- We rented our house on December 14th 

- My wife and kids moved from HI to NC on December 28th at which point we moved into the house (I stayed in temporary housing until then)

 

Questions:

1. What is my move date?

2. What is my wife's move date?

3. Can my wife and I file state returns "Married, filling jointly" with different move dates?
