While the dates aren't exact (probably not even close), I'll go with them.
Just as the Bible is silent as to Jesus' childhood until age twelve, it provides no insight on the days between December 26th and January 1st. So, we're left to speculate.
Your attempt at answers is as good as mine. We cannot return to that point in history to discover the answers. If we are followers of Jesus, we can, however, return in our minds to the time (or gradual process) when we chose to accept Jesus as Lord, the time of our birth - second birth that is.
The first few days of Jesus' life were important. Every day of life is important.
