Photo Organization

I have this photo of my wife and I from when we first started dating on my computer. It's poorly lit and we're both a little glassy eyed, but I want to keep it since it's such a rare shot. The problem is that whoever took the photo had the date on their camera set in the year 2017, so in all of my photo sorting and editing programs, this one picture always appears at the very top of every list, so I see it all the time. I've tried to sort out how to change the meta data so I can put it in chronological order like all the rest of my photos, but it's beyond my skills. This is not the photo I would have picked had I known I would see it every day. I can't even imagine what a total disaster the computer is of the guy who took the photo.
