NHS Trusts - find out what they did in the 18th Century

Researching the history of the Wednesbury Old Canal (where?), I tried to find out what else was happening in the world in November 1769, so I Googled that date.

As well as plenty of interesting, relevant information, on the first page of hits are a number of NHS Trust online calendars. Do these calendars actually exist to show events in the mid 18th Century or are they just dynamically created?

Randomly put in a date....November 1345...and you get plenty of blogs and an event calendar for the town of Barnstaple, Massachussets showing that nothing happened that month. Not entirely surprising, given that November 1345 is 294 years before the town was founded.
