Some people have Synaesthesia (a rare condition that causes people to experience more than one sense at once) so for them a day could have a color, a smell or a sound.
If you have, or if you were to have, Synaesthesia what color, smell, sound or feel does Thursday have for you.
I don’t have it but if I did I could imagine Thursday smelling like a newspaper and fresh coffee. A little casual and slow in morning, thinking about the weekend coming up. I suppose having a recollection of what a morning newspaper smells like sort of dates me.
