Litany of the Saints
Rogation days are days of prayer and fasting in Western Christianity. They are observed with processions and the Litany of the Saints. The so-called "major" rogation is held on 25 April; the "minor" rogations are held on Monday to Wednesday preceding Ascension Thursday. The word "rogation" comes from the Latin verb "rogare", meaning "to ask", which reflects the beseeching of God for the appeasement of his anger and for protection from calamities.
