In 2017 Assumption of Mary takes place on August 15. That is a solemnity of the Roman Catholic Church, made a dogma in 1950 by Pope Pius XII. Assumption of Mary is an official holiday in Catholic shaped European countries like France, Spain, Italy, Austria, and some parts of Switzerland, Germany and Greece and others. This day commemorates the assumption of Mother Mary's body and soul in heaven. It is also called the Falling Asleep of the Blessed Virgin Mary or the Feast of St. Mary the Virgin, Mother of our Lord Jesus Christ.
A famous custom on Assumption of Mary is the collection of herbs. People make bouquets of seven different herbs symbolizing the seven sacraments. These herbs, like St. John's wort, common centaury, wolf's bane, lady's mantle, valerian and eyebright get consecrated by a priest during church service. After that they serve as a guard for estates and homes. That goes back to a legend according to which Mary's grave had been opened by the disciples of Jesus who did not find Her corpse there, but only blossoms and herbs.
Assumption of Mary is the beginning of the 30 days during which numerous Mary related processions and pilgrimages take place. Plants that bloom in that time are considered to have healing powers. This time period ends with the Feast of the Most Holy Name of the Blessed Virgin Mary on September 12.
Going by the believe of the Catholic Church Mary conceived her son Jesus without the original sin, meaning the sin of Adam and Eve, when they ate from the tree of knowledge. As the first human being, Mary had been absorbed to heaven with her body and soul. Being free of any sin Mary did not have to go through the Last Judgment and purification by purgatory.
