There's been speculation the nun who worked with the destitute and dying in India would be made saint by Pope Francis in a ceremony during the Holy Year, which runs from December 8 till November 20, 2016.
The Italian bishops conference daily Avvenire today, citing Italian news agency AGI, called September 4 a "probable" date.
Vatican spokesman the Rev. Federico Lombardi stressed that Francis still needs to approve a miracle attributed to Mother Teresa's intercession before she can become a saint.
