I want to know the answer to the following question:
When was the next session announced?
All the background I'm provided with is that "In his journal in 1959 during a spiritual retreat, John XXIII made this remark: "I always think of Pius IX of holy and glorious memory, and by imitating him in his sacrifices, I would like to be worthy to celebrate his canonization".". Is that enough to answer the question?
Answer: no
