Last year one day just vanished from my memories. I usually have no big problems remembering the day as I can just look it up on my PC, but that one day I thought it was Tuesday while it was Wednesday. And no matter how hard I tried, I just couldn't remember what I did on that Tuesday. Interestingly, the same happened to a friend of mine. I didn't trust my PC, cell phone etc. on that day.
