May 9th, 1947

I had a dream a couple of days ago that dealt with a certain day in the past. The date was written on the palm of my hand or my arm or something. Anyway, I meant to look it up when I woke up, but got distracted. Yet the date still stayed with me. Kind of. I wasn't sure if it was May 7th, 1947 or May 9th 1947. So I looked up both a few minutes ago. The former resulted in nothing. Not even a notable birth. However, May 9th 1947 is Victory Day in the Former Soviet Union...
