It can be on a day to day basis, but if it’s a chronic thing, it’s usually (in retrospect, of course) easy to differentiate. Person 1 goes home every night after work and feels like they want o watch TV, so they do, every day for a year. Person 2 goes home every night and feels the same, however they meet friends/go to the gym/read a book/_something_ different once or twice a week. There’s a world of difference in retrospect.
