I once created a site that shows you interesting things that happened a round number of days ago. You can also check when you special day birthday is, for example, at what date do you turn to be 17000 days old ?

Although the site even made the news once, I didn’t bother to maintain it, but if you’re interested, take a quick look at the Count In Days site. Perhaps you can surprise someone who isn’t aware a special birthday is coming up soon…
