I was interested to see Goldsmith mention a number of customs that were celebrated in mid-C18th Georgian England ( book was first written in 1760s').

The vicar mentions in his new neighborhood, a farming community, the local people observed certain festivals.
'They kept up the Christmas carol' (ch.4) So Christmas carols were sung in Georgian England!
They ate pancakes at Shrovetide, celebrate Valentine's Day. Does anyone know what sending true love knots might mean?

They showed wit on first of April was and cracked nuts on Michaelmas eve. (ch.4)

I wonder if such festivals were generally celebrated or only certain counties of mid-Eighteenth century England.

My impression is the Vicar and family travelled to an isolated, poorer parish. However, the farming people knew how to make merry!
They even turn out to greet the Primroses in best dress, with music and a feast.

Does Jane Austen refer to any of these festivals? I think Mrs Bennet mentions Michaelmas.
