Please check the answer to this question, Why do some days feel fast and others feel slow?, think that is the answer you are looking for.
2$\begingroup$ Thanks for pointing out that question. It seems the current questions is a duplicate of that one. This, however, does not constitute as an answer since it is just a link, but is a comment instead. Still, a very valuable one. I've flagged it for the moderator to move it to the comments, so you don't have to delete it. $\endgroup$ May 23, 2017 at 9:30
