[Nicky91]

The Feast of the Ascension of Jesus Christ, also called Ascension Day, Ascension Thursday, or sometimes Holy Thursday, commemorates the Christian belief of the bodily Ascension of Jesus into heaven. It is one of the ecumenical (i.e., universally celebrated) feasts of Christian churches, ranking with the feasts of the Passion, of Easter, and Pentecost. Ascension Day is traditionally celebrated on a Thursday, the fortieth day of Easter (following the accounts given in Mark 16:19, Luke 24:51 and Acts 1:2), although some Christian denominations have moved the observance to the following Sunday. In the Catholic Church in the United States, the day of observance varies by ecclesiastical province.
