On-this-Day

Just discovered these 'on-this-day' pages not long ago (great for trivia buffs and just random reading): from NYT, on-this-day, searchable by month and day. The BBC does this as well.

And going in the other direction, Wikipedia has some interesting timelines of the future - the future in forecasts, of the near future, and the far future.
Pretty mind-boggling, thinking of the future in terms of billions of years!
