All Saints Day was the celebrated on 1st November every year. It was a feast day in honour of all the saints and martyrs and was established because there were not enough days in the year to commemorate the lives of all the saints. Pope Urban IV said of it: “Any negligence, omission and irreverence committed in the celebration of the saints’ feasts throughout the year is to be atoned for by the faithful, and thus due honor may still be offered these saints.”
