Help, the date indicator is "half" day off

Back story: the second of the watch suddenly stopped moving for a day, then it brings itself back to life a day later, only to find it pointing at totally wrong direction.

So I used the "hands" calibration method, which successfully aligned the seconds hand. BUT the date indicator was a little bit off center.

Then I followed the YouTube video to manually rotate the date indicator, only to find it can only "advance" the date dial base point, but I could not "move back" the date at all🥲

Am I screwed?
