Michaelmas became the fixed date for the feast otherwise associated with Autumn Equinox or the harvest. As early as 1014, the laws of Ethelred in England prescribe a three day fast for all Christians before the feast. Servants weren’t allowed to work during these days. Michaelmas was a time when rents were due, and rents were often paid in food. The traditional rent for Michaelmas was a goose.
