On September 29, the liturgy used to celebrate all the angelic choirs together.
That is why, for a long time, there wasn’t a separate feast for the Guardian Angels.
The first time we see such a celebration is in Valencia, a city that, at the beginning of the 15th century, kept a special feast in honor of the city’s own angel.
Still, it wasn’t until the end of the 17th century that the custom of honoring the Guardian Angels with their own liturgical feast spread more widely—first across the Iberian Peninsula, then in France, and later throughout the Empire.
The original date of the celebration was March 1. Later, after some changes, it was moved to the first liturgically free day after the feast of Saint Michael: October 2.
