No, that’s not day 1, its day (negative) 1.
Day -1 doesn’t exist, Thats cheating, you say? Well this is just part of my pre-365 day photo mission. I will officially start tonight, but until then here are some photos I took a couple days before. I’ve been trying to start this project some days ago but even since then i’ve missed some days. So starting after this I will begin with positive integers.
