In page Visitation (Christianity):

"

In the calendar of the Anglican 1662 Book of Common Prayer, the Visitation of the Blessed Virgin Mary is a black-letter day marked on July 2,[6] although many modern Anglican calendars now celebrate the Visitation on May 31 in line with the changes made to the Roman calendar.[citation needed] The Catholic and Lutheran churches of Germany have also retained the date of July 2.[citation needed] Similarly, the Catholic Church in Slovakia has also retained July 2 because of an important national pilgrimage to the Basilica of the Visitation in the town of Levoča that has been held in the first weekend of July since the 13th century.[citation needed] Traditionalist Catholics, who use a pre-1970 calendar, also observe July 2.[citation needed]
