Saint Joachim

Extracted from the Wikipedia article Joachim.
In Catholic tradition
No liturgical celebration of Saint Joachim was included in the Tridentine calendar. It was added to the General Roman Calendar in 1584, for celebration on 20 March, the day after the feast day of Saint Joseph. In 1738, it was transferred to the Sunday within the Octave of the Assumption of Mary. As part of his effort to allow the liturgy of Sundays to be celebrated, Pope Pius X (term 1903–1914) transferred it to 16 August, the day after the Assumption, so Joachim may be remembered in the celebration of Mary's triumph. On May 28, 1906, Pope Saint Pius X introduced the indulgence of 300 days, that can be obtained once a day, for each invocation of "Saint Joachim, spouse of Saint Anne and father of the Blessed Virgin".
