I just received a Vatican Information Service Special Edition brief in my Inbox. Here are the important bits:
"Tomorrow, Divine Mercy Sunday, at 10.30 a.m., a Mass for the repose of the soul of the Holy Father will be celebrated in St. Peter's Square, presided over by Cardinal Angelo Sodano.
"At 12 noon, the Marian prayer of Easter time, the Regina Coeli, will be recited.
"The body of the late pontiff is expected to be brought to the Vatican Basilica no earlier than Monday afternoon.
"The first General Congregation of Cardinals will be held at 10 a.m. on Monday April 4 in the Bologna Hall of the Apostolic Palace."
It's all official, straight from the Holy See Press Office Director Joaquin Navarro-Valls.
Please note that daylight savings time begins in North America Sunday morning at 2:00 a.m. At this time, clocks will move ahead one hour. At the time the Mass is scheduled to begin, the Eastern and Central time zones will have moved forward one hour. But times zones west of this will not have done so yet. Therefore, the 10:30 a.m. CET start time in Rome corresponds to 4:30 a.m. Eastern Daylight Time and 3:30 a.m. Central Daylight Time, but 1:30 a.m. Mountain Standard Time and 12:30 a.m. Pacific Standard Time. Confusing, but I hope that clears things up a bit!
