Don't worry too much about the dates, it's problably a spelling mistake. Remember that pictures were not developped before months after they were taken and sometimes years when people kept the rolls hidden (in case of censured material by the Germans) . Besides pictures were rare and were a real luxury for civilians in a occupied country. So by the time they were developed the memory of the exact date could be vague. I'm actually surprised this picture was developped. Most pictures I have are from the 1944-1945 period because other simply were not taken because they were illegal and taking certain pictures meant arrest and more.
