SASI-TIME.
As more and more states move away from the old, tired model of children of divorce and separation being with dad every other weekend, and toward the model of equal time for the kids with each parent, it has gotten more and more complicated to try to measure the number of days a child is with each parent. This is what it used to look like:
We'd haul out a yearly calendar and try to manually count the number of overnights the kids had with mom and the number with dad Why? Because at least in Maryland, and also in other states, the number of days a child has with each parent affects other areas of law, like child support. It got even more complicated when there was more than one child, and the parents had what is known as "split" custody (that's what happens when one parent has most of the time with one child and the other has most of the time with the other child.
Add in holidays, school breaks and all the rest and you needed a computer to figure out the number of days and the percentage of time each child in a single family spent with each parent. Wait! That's what SASI-TIME does!
Trust me, I've tried it and as far as I can tell, it is the only product out there that does this, with so many variations. I liked it. And it's internet-based so my Mac office can use it with ease. I can't tell you it's perfect, but so far, it's all I can find out there that does so much in one place and I was impressed.
