The Church took over the autumn equinox for St Matthew, patron saint of tax collectors and bankers, and fixed this to 21 September. In the English Midlands, St Matthew’s Day is viewed as the first of three windy days, also called ‘windy days of the barley harvest’.as One of the many traditional English sayings associated with the day is:
St Mathee, shut up the Bee;
St Mattho, take thy hopper and sow;
St Mathy, all the year goes by
St Matthie, sends sap into the tree 
This indicates that it is time to shut up the bee hives and make the autumn sowing.
