Michaelmas, (also known as the Feast of Saints Michael or the Feast of Saint Michael and All Angels), is a Christian festival observed in some Western liturgical calendars on 29 September.
In Christianity, the Archangel Michael is the greatest of all the Archangels and is honored for defeating Satan in the war in heaven. He is one of the principal angelic warriors, seen as a protector against the dark of night, and the administrator of cosmic intelligence.
In Anglican and Episcopal tradition, there are three or four archangels in its calendar for 29 September feast for St. Michael and All Angels: namely Michael, Gabriel and Raphael, and often, Uriel. The Bible itself identifies only Michael as an archangel (Jude:9), although in I Thessalonians
4:16, there is the implication that there is more than one archangel.
Gata de Gorgos in Spain, where I live, has St. Michael as its Patron Saint.
The local church is named after him (Iglesia de San Miguel Arcángel), so for the catholic community of Gata de Gorgos the Fiesta of San Miguel is a major event.
The 29th of September two masses are held for San Miguel, at noon and at seven o'clock in the evening. At eight o'clock a procession is held through the streets of Gata ending in the little Chapel on the Hill, here a celebration is held by the collective clergy. Hundreds of people take part in it, which is a quite impressive sight.
