Here is an example of a Who Has Custody's screen for December for "Han" and "Leia" who are using the 2-2-5-5 rotation schedule. Leia normally has custody of their child, Jacen, on Mondays & Tuesdays, Han has Wednesdays and Thursdays. This year Leia has custody for the Christmas holiday from Noon on the 24th until 6:00 pm Christmas day. Han has custody for New Year's eve, and for Jacen's birthday on the 14th.
