I have, actually. I also adjusted the days, months, and year to see the changes.
Horoscopes work by implementing something called the Texas Sharpshooter Fallacy. Let me explain:
Abraham Lincoln and John F. Kennedy were both assassinated by a man with three names, 15 letters long: John Wilkes Booth and Lee Harvey Oswald. Neither killer would make it to the trial. Both men were shot on a friday, sitting next to their wives. Lincoln was in the Ford Theatre, while Kennedy was in Lincoln made by Ford. What are the odds?
Imagine a Texan going out every morning to shoot his gun at the side of his barn. He does this for months. After a while, clusters of bullets are going to appear. It just happens. Then, the next morning, he takes a bucket of paint and paints a bullseye on one of the larger clusters. To all outside viewers who stumble on this it looks like he's a pretty good shot.
Now, back to the story above. I told you points that completely matched up, no matter how random. But there are thousands of points that I just didn't mention. When you look at two different events, especially when they're tragic, you tend to only see the similarities.
You see, we're born looking for patterns. We try to see clusters where chance events have built up, and that's exactly what horoscopes prey on.
They generalize, make vague remarks, and rely on you to give them meaning. If they get something wrong, you just say "Well that's wrong, BUT EVERYTHING ELSE IS RIGHT!" Read up on the Forer Effect if you don't believe me:

When you desire meaning, when you want things to line up, you see patterns everywhere. Order makes it easier to be a person, to navigate this sloppy world. Picking out clusters of coincidence is a predictable malfunction of a normal human mind, don't feel bad.
