The way I typically do planning is kind of like a calendar. But time isn’t that important. Duration is. And order usually is.

I just list of everything I plan to do in order and try to guesstimate how much time it takes. It is a decent way for me to make plans a bit more realistic than if I don’t include time.

I know how much time things take (most of the time), I know how many hours there is in a day.
