] "Gracechurch-street, Monday, August 2". (P&P Chapter 49)

Oh, a goodie! (Hangs head for not spotting it herself)

] Does anyone know if there is an on-line resource to know if it's possible to have one year Tuesday November 26h and the following year a Monday August 2nd and what years of late 18th and early 19th centuries could match that criteria?

I've got a manual one, but it involves some arithmetic. I'll do the calculations if nobody can come up with an on-line date calculator (which would be very useful: I had one but it disappeared when I changed computers).
