I guess I can break some of my stuff down, but a schedule is not my thing. I view the tanks and feed them every day. Well, sometimes I forget or am just that busy or gone. I also add algae each day when I remember (although, all I have to do is look at the fish, they let me know).
I do more water changes on my smaller tanks (40g/20g/6g). My 210g will be fine until I have the water or the inclination to do one.

I try to get at least two in a month on the smaller tanks and one on the larger. With the tank water change, I scrub the sides (including backs) well, clean out the skimmer, check the carbon rx, check the algae scrubber (more like weekly on this one), clean the overflow box and powerheads.
Now, I pull algae as I see it getting a bit too much. blow off frags or rock when needed with baster (mostly my smaller tanks).
Then, every so often I will clean all the pumps. This occurs when I decide to do a sump clean usually or at least twice a year. More for some pumps. I remove and clean the chiller in the winter. Do RO/DI stuff usually in Jan. Bulbs as needed (I run MH and T5s) on all systems.
Calibrate my probes once in a blue moon. Check my salinity when I do water changes. That is all for me. I do not test anything else. Terrible I know. I used to, but now, I can see by things in the tank what is good, bad or out of whack.
Oh, I glance at my CaRx bubble counter to check it is still on time and the effluent. Glance at the tank too.
When I travel, I have a very scheduled out day by day for babysitter. If only I followed it.
Oh, I scrape main sides as needed or I get to it.
I record my maintenance in a log (when I remember) along with any things I notice in my tank or changes of anything. QTs are all logged too. This part I am better with.
