"Rogation" comes from the Latin "rogare," which means "to ask," and Rogation Days are days during which we seek to ask God's mercy, appease His anger, avert the chastisements He makes manifest through natural disasters, and ask for His blessings, particularly with regard to farming, gardening, and other agricultural pursuits. They are set aside to remind us how radically dependent we are on God through His creation, and how prayer can help protect us from nature's often cruel ways. Hence, its mood is somber and beseeching; its liturgical color is purple.
