Pope Francis kept annual Holy Week appointment visiting dozens of inmates in a Rome prison on Thursday. The 88-year-old is still recovering from pneumonia.

Pope Francis has visited Rome’s main prison and kept an Easter season appointment to spend Holy Thursday among the least fortunate.

The Vatican on Thursday opened the most solemn period of Holy Week with a recovering Pope Francis largely on the sidelines, as cardinals were designated to take his place presiding over the most important liturgical services leading up to Easter.

Holy Week kicked off this week with Palm Sunday on April 13. Here's the remaining significant dates for the week until Sunday's Easter holiday.
