well what I initially wanted was an extended weekend holiday for Thanksgiving every other year. And for xmas, sharing the day. One parents gets from xmas eve 6pm to xmas day 3pm. Other parent gets xmas day 3pm to dec. 26 6pm until the child reaches the age of five. Every other year, one parent gets xmas eve and the other takes the 2nd half. I think it is only fair that we both have some time on xmas day.
Actually a more common division if you are splitting the actually holiday, for Christmas, is 6PM Xmas eve until noon on Christmas day, and noon on Christmas day until whenever, depending on the rest of the holiday schedule.
Eventually, you are going to have to split "Christmas break" in half. A common division is one parent gets the first week, and one gets the second, and whoever's week does not include Christmas, gets noon to 9 PM on Christmas Day.
A common split for Thanksgiving weekend is that one parent gets Wednesday evening to Thanksgiving Day at 5 or 6 PM, and the other gets the rest of the holiday weekend, then it reverses the next year.
One parent getting from Christmas Eve to New Years Day is not a fair division of the holiday.
