耶稣升天节是纪念主耶稣基督在复活四十日后升天一事。这在《使徒信经》和《尼西亚信经》都得以确认。

由于复活节在星期日，故本节在星期四庆祝。

The Feast of the Ascension of Our Lord and Savior Jesus Christ, also known as Ascension Thursday, Holy Thursday, or Ascension Day, commemorates the bodily Ascension of Jesus into heaven. It is one of the ecumenical feasts (i.e., universally celebrated) 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 count given in Acts 1:3), although some Christian denominations have moved the observance to the following Sunday.
