Every day is the same to me in terms of the relative time that I feel. So, there's no such thing as "longer days" and "shorter days" for me.
Even if there is a small difference, I think it depends on what I did during that day and how it went for me. The relative time doesn't matter because some of the "short days" can go well for me while others can be a lot worse for me. The same thing with the "long days" (again, because some are good and some are not that good). The point is that my preference depends on how I'm going to spend my time during the day as opposed to whether the day feels long or short to me. I don't care about the relative time because I don't feel that much of a difference anyways.
