"On this day" travel reference

We've all seen the calendars and books and web sites that tell us "On this day in 1969, Neil Armstrong became the first human (as far as we know) to set foot on the moon," etc. That's interesting because it encourages us to remember or imagine interesting moments in history.

When I'm traveling, either on business or for pleasure, I'd like a reference for the locale in which I'm traveling that tells me "on this day, in this city, ..." That way I could spend the whole day mentally playing with how the historical event relates to what I'm experiencing as I live that day in the historical surroundings of the event. I think that could make for an interesting diversion from a business trip, or an entertaining theme for a pleasure trip. And I think that, being in an unfamiliar and interesting place, I'd be more likely to keep the historical event fresh in my mind than if I hear about it on the way to work and it's not as relevant.

I wouldn't want it to say "On this day in 1587 Elizabeth I signed the death warrant for Mary, Queen of Scots," and the next day to say "On this day in 1587 Elizabeth I had tea." Rather, on the second day, it should say "On this day in 1940, the first bombs fell on London in the Battle of Britain" (Assuming those two days are actually adjacent, though I'm sure they're not).

I'd think there's been enough history in nearly any major city to pull this off. Where actual history doesn't provide an interesting event, alx's Fiction Calendar could perhaps be consulted. It could be published in a wide variety of formats, especially electronic ones.
