"The Calendar marks dates according to the Gregorian and Islamic calendars, and contains significant dates in terrorism history, as well as dates that terrorists may believe are important when planning 'commemoration-style' attacks." Conveniently available in both online multimedia format (deep link to the timeline itself), as well as a printable version (63 MB PDF). [more inside]

For 170 years, crossing the Channel from the UK to France would have brought you 11 days forward in time, and crossing back would have brought you 11 days earlier. Why? Because the Church of England wasn't about to adopt a new Calendar instituted by a Catholic pope. After all, if the old style was good enough for Caesar.... In fact, it took over 300 years for the new Gregorian Calendar to come into use throughout Europe, causing, no doubt, more than a few missed lunch dates as people forgot to convert between them as they traveled. There are, of course, many other calendars in use around the world, and no shortage of people suggesting that let's do the time warp again.
