This was that common feeling of not knowing quite what day it was, but one that persisted an unusually long time. Was it Wednesday morning, in which case I had two shifts in front of me before I had a day off, or was it Thursday morning, in which case I had only the one shift left and would have tomorrow free?
I searched my memory both forward and back, asked myself three and four times — and still I didn’t know. I could remember certain aspects of the preceding day, but nothing about those aspects identified the day on which they occurred. I gradually came to feel that not only did I not know whether it was Wednesday or Thursday, but did not know, on the basis of thinking alone, how I might come to know.
Ultimately I established it was indeed Thursday morning because I realized I only had one fresh work shirt left (If I’d had two it was likely to be wednesday, three tuesday, etc.) but I couldn’t confirm it independently through my memory until sometime much later.
