The latest in the series Google hacks, Google Date lets you enter a date (day, month, year) and it will return what Google has to say about this date in a sentence or two, three results per search.
Google doesn't optimize searches for relevance when it comes to dates. So the results aren't famous-person-dates, but random events out of the lives of random people. It makes the world seem strangely connected.
The difference between America and England is that the English think 100 miles is a long distance and the Americans think 100 years is a long time.
