I don't know about you, but for myself I find the days kind of blur together (especially (during-COVID, post-COVID) WFH).
I rarely need to know day-of-month.
My favourite ever gift from friends was that people bought me (last century, long before smartphones) a 24 hour radio synchronized digital alarm clock which knew the day and full date including year. Because while often I know 0600 from 1800, not always, and on a particularly bad day maybe I'm not even sure which week this is. I didn't need the year really, but it felt appropriately completionist, just in case.
Also, Seiko's watchfinder won't let you filter based on whether or not it has a DoW complication; very annoying.
Even work from home is immediately cleared up once I look at my computer screen.
In my case, a combination of having no kids, being entrepreneur (self employed) and having ADHD.
I have to ask people "is it tuesday or monday today" at least once a month. It gives strange looks. People often look at me, clearly trying to figure out if I'm bullshitting them. But I honestly forget such -for me- unnecessary details.
But I guess having children, or a regular job, or both, gives a firm anchor of weekends and weekly rhythms. I've had long periods of jobs were I too had such anchors.
Best way to explain it, is when you are on holiday (in one place), for a few weeks, you also don't know what day it is. I guess I always have holidays?
I ended up settling on no-date watches, as I find setting the date to be annoying, and it’s not something I need that often. When I do need it, I have my phone. I think I’d ultimately feel the same way about a day of the week complication.

But most people always know exactly what day of the week it is, but rarely know the date. (The only time I'm ever unaware of the day is on vacation occasionally.)
And the date is needed basically every time I sign anything on paper, as you almost always put a date next to any signature -- whether you're writing a check, filling out forms at the doctor's office, signing consent forms for an activity, and so forth.
I know a retiree that got this as a (sort-of, sort-of-not joke) gift because she mentioned that she sometimes forgets the day:

(Works best near a window where the radio signal from Colorado can be heard.)
I think it's not having the "regular job". I have a kid whom I daily bring to day care and I regularly don't know what weekday it is.
Reminds me of the Downton Abbey joke(not really a joke) about "what is a weekend?": https://www.youtube.com/watch?v=onUkNsXks54
