Not sure if that was the case in the past though or when it would have changed. I don't have any reason to doubt your story, so it's possible.
What you describe would be a calendar days setup I guess and I agree that changing that silently (on the same account) would piss me off. There might be good reasons for them to change it but not without reaching out to affected users. Or did you only see this new behavior on a different/newer account?
I'd say you should raise that with their support team! It should be fairly easy to find evidence of that change for Stripe, right? And you should also be able to find evidence of the old behavior (a bit of search work in the balance history but doable).
Still possible that your account is much older and you were grandfathered and then finally moved over to the new behavior long after this was standard for everyone. I'd really just check with them.

EDIT: I tried to go back on the wayback machine and it said business days for quite some time before last year (https://web.archive.org/web/20170905023631/https://stripe.co...).
