> constantly doing math with time in my head.

What, exactly, are you calculating? Would it help you to see the total of the non-scheduled hours for each day, inside a specific range (e.g. 07:00 until 22:00)?

I use the Nextcloud calendar app and sync with my Android devices using the CalDav protocol. I have one calendar for work, another for personal. They all display on the same monthly or daily view, just with a different background colour.

It is really hard to separate work from personal life as freelancer. Maybe OP could start there, because this calculating problems starts there. Setting working hours can help and IMO can't be that hard even with kids - I did it for some time. And when you're looking for flexible calendar - you won't find anything better than small paper calendar, pen and cheap casio watch.

I get you, to be honest, I think other people are a lot better than I am at keeping their organization in their heads. I just suck at it real bad.

Yeah I was thinking I should give that a shot first...

Good luck! :) I survived college with leuchtturm1917 - maybe it's some good staring point.

Thanks! just bought an hobonichi techo. It's ridiculously expensive, but I am thinking that if it's expensive, I'll feel bad if I don't use it :-D
