In case you, like I, have trouble trying to remember the time difference to Rome, I have placed a clock with Rome time on the front page and on the sidebar of my blog just to the right.
Now for the smoke signals, they will occur twice a day according to the press release, unless, of course, we have a new pope:
Since there are two votes each morning and afternoon, Fr. Lombardi stated that the 'fumata' (smoke signalling the election or non-election of a pontiff) that is produced from the burning of the ballots from those two voting processes could be expected around 12:00pm, in the case of the morning, or 7:00pm, in the case of the evening, unless the first of the two votes produces an election. In such an instance, the “fumata” would obviously take place earlier.
O God, eternal shepherd, who govern your flock with unfailing care, grant in your boundless fatherly love a pastor for your Church who will please you by his holiness and to us show watchful care. Through our Lord Jesus Christ, your Son, who lives and reigns with you in the unity of the Holy Spirit. one God, for ever and ever. Amen.
