This week Christians celebrate the Feast of St. Matthew, to be followed by Michaelmas.

From Wikipedia:

"Michaelmas, the feast of Saint Michael the Archangel (also the Feast of Saints Michael, Gabriel, Uriel and Raphael, the Feast of the Archangels, or the Feast of Saint Michael and All Angels) is a day in the Western Christian calendar which occurs on 29 September. Because it falls near the equinox, it is associated in the northern hemisphere with the beginning of autumn and the shortening of days. In medieval England, Michaelmas marked the ending and beginning of the husbandman's year."

At British universities, the academic year used to begin late in September, and the first part of the academic year was therefore called "Michaelmas term."

The Sanctuary of St. Michael the Archangel (Santuario di San Michele Arcangelo) is a sacred cave and popular Catholic shrine near San Giovanni Rotundo. Here the Archangel Michael is said to have appeared in 490, 492 and 1656 and consecrated the shrine himself.
