I know this isn’t exactly what you meant, but I thought it a pretty cool feature. http://www.worldofquotes.com has a “Daily Calendar” of What’s happened in the past. Say, for instance, on a roleplay night you wanted to see what happened in 1871. You can pick that day’s date, scroll through to 1871, and it’ll tell you the nifty things that happened on that particular date. Has alot of useful information on deaths, Changes of the Crown, births, etc.
