Page "Catherine of Siena" Paragraph 20

Pope Pius II canonized St Catherine in the year 1461.

Her feast day, at the time, was not included in the Roman Calendar.

When it was added in 1597, it was put on the day of her death, April 29, as now, but because of a conflict with the feast of Saint Peter of Verona, which was also on April 29, it was moved in 1628 to the new date of April 30.

In the 1969 revision of the Roman Catholic calendar of saints, it was decided to leave the celebration of the feast of St Peter of Verona to local calendars, because he was not as well known worldwide, and Saint Catherine's feast was restored to its traditional date of April 29.

Some continued to use one or other of the calendars in force in the 1628 – 1969 period.
