IMO put as much detail as possible, especially around times. A good example is tracking when your ex left and returned, that entry is good. Also track when you leave the house, go to work, come home, kids are at school or in others care etc. You can always summarize it at a higher level later.

Personally this sounds like this is a feat for you, something out of the ordinary that you deserve credit for doing the first time. Keep it objective and factual, you hosted a birthday party for D6 at parents house from 2pm - 4pm, 4pm - 5pm you cleaned up after the party while kids did xyz. Don't give the judge the impression that you are taking on tasks just to journal and look good.
One big goal with a journal entry is that it clearly shows who was parenting your children, you or your ex or others such as at school or with a relative. And what activities you were doing with the children during your time. When you split and live apart it is easy to tell who was parenting the children because they'll be at one house or the other. When you're still living in one house you need a lot of detail to make that clear. Ideally as you summarize that detail into evidence you can show a picture of the parenting time status quo.
