The Solemnity of the Most Sacred Heart of Jesus will be observed on June 23 this year, 19 days after Pentecost.
Sources say devotion to the Sacred Heart of Jesus is nearly as old as Christianity. Its observance can be traced back to about the 11th century, but it was not included in the Church calendar until 1856, when Pope Pius IX extended it to the universal Church. In the late 19th century, Pope Leo XIII raised it to the rank of a feast.
