The Feast Day of St. Clare of Assisi (11 August) celebrates the 11th and 12th century Italian saint who founded the Order of Poor Ladies (later renamed the Order of Poor Clares.) She is known for several miracles, the most famous being the miracle during the Saracen invasion in 1240, where she held the Blessed Sacrament and caused the attackers to flee in fear. Other miracles include multiplying loaves of bread for her sisters and healing the sick through her prayers.

She is a patron saint of several things, including eye disease, goldsmiths, laundry, television, bicycle messengers, good weather, needleworkers, remote viewing, extrasensory perception, fertility, Santa Clara, California, Santa Clara Pueblo, New Mexico, and Obando, Bulacan.
