What will happen today in the first day of the Conclave (Tuesday, 12 March 2013)? All the time noted below are in Rome time (CET, Central European Time, 1 hour ahead of UTC (UTC+1)).

Some event are live from Vatican Player at http://www.vatican.va/video/ and the live recording from Rome Reports : http://www.romereports.com/palio/modules.php?name=Content3&pa=showpage&newlang=english&pid=47#.UT4XGVeJegH

1. (Live) Mass for the Election of the Roman Pontiff / Missa pro Eligendo Pontifice : 10 am. This Mass will officially begin the Conclave and will be offered for prayers for the election of the Pope.

2. Cardinal-electors leave the Domus Sancta Marthae where they stay for the Pauline Chapel : 3.45 pm

3. (Live) Cardinal-electors begin the procession into Sistine Chapel from Pauline Chapel, while singing Veni Creator Spiritus and the Litany of the Saints : 4.30 pm

4. (Live) Oath of secrecy by the Cardinal-electors and the extra omnes order by Monsignor Guido Marini : 4.45 pm, then meditation by Cardinal Prosper Grech of Malta (2nd meditation)

5. Conclave and first ballot : about 5 pm – 7 pm, smoke should appear between 7-8 pm Rome time. If white, means a new Pope has been elected, but this is unlikely to happen. (Smoke and the chimney can be seen live through either Vatican Player or Rome Reports page I mentioned above)

6. Vespers celebrated by the Cardinal-electors : 7.15 pm

7. Cardinal-electors return to Domus Sancta Marthae, their residence during the period of the Conclave : 7.30 pm

These are just rough timing, and as this is the first ballot, the Cardinal-electors may still need time, especially the first-timers, in getting used to the rules and proceedings of the Conclave and thus might be delayed slightly.
