When do you celebrate the birth of the church?

Answer 1

Roman is an epithet first commonly used in England after the protestant revolt to describe the Catholic Church. It is rarely used by the Catholic Church.

Pentecost Sunday:

On the day of Pentecost when the seven weeks of Easter had come to an end, Christ's Passover is fulfilled in the outpouring of the Holy Spirit, manifested, given, and communicated as a divine person: of his fullness, Christ, the Lord, pours out the Spirit in abundance.

On that day, the Holy Trinity is fully revealed. Since that day, the Kingdom announced by Christ has been open to those who believe in him: in the humility of the flesh and in faith, they already share in the communion of the Holy Trinity. By his coming, which never ceases, the Holy Spirit causes the world to enter into the "last days," the time of the Church, the Kingdom already inherited though not yet consummated.

When the work which the Father gave the Son to do on earth was accomplished, the Holy Spirit was sent on the day of Pentecost in order that he might continually sanctify the Church. Then "the Church was openly displayed to the crowds and the spread of the Gospel among the nations, through preaching, was begun. As the "convocation" of all men for salvation, the Church in her very nature is missionary, sent by Christ to all the nations to make disciples of them. Thus, Pentecost Sunday about the year 33 AD is considered the birthday of the Church.

Answer 2

Roman Catholic AnswerThe birthday of the Church is considered to be Pentecost - fifty days after Easter, the day the Holy Spirit descended on the Apostles in the upper room.

from The Catechism of the Catholic Church, second edition, English translation

767 "When the work which the Father gave the Son to do on earth was accomplished, the Holy Spirit was sent on the day of Pentecost in order that he might continually sanctify the Church." (Lumen Gentium 4; cf. Jn 17:4) Then "the Church was openly displayed to the crowds and the spread of the Gospel among the nations, through preaching, was begun." (Ad gentes 4) As the "convocation" of all men for salvation, the Church in her very nature is missionary, sent by Christ to all the nations to make disciples of them. (Cf. Mt 28:19-20; Ad gentes 2; 5-6)

1076 The Church was made manifest to the would on the day of Pentecost by the outpouring of the Holy Spirit. (Cf. Sacrosanctum concilium 6; Lumen Gentium 2) The gift of the Spirit ushers in a new era in the "dispensation of the mystery" - the age of the Church, during which Christ manifest, makes present, and communicates his work of salvation through the liturgy of his Church, "until he comes." (2 Cor 11:26) In this age of the Church, Christ now lives and acts in and with his Church, in a new way appropriate to this new age. He acts through the sacraments in what the common Tradition of the East and the West calls "the sacramental economy"; this is the communication (or "dispensation") of the fruits of Christ's Paschal mystery in the celebration of the Church's "sacramental" liturgy.

The "birthday" of the Christian Church is typically celebrated on Pentecost Sunday. On Pentecost, St Peter, upon receiving the Holy Spirit in the form a tongue of fire resting upon his head, stood up and proclaimed the Gospel. On that day several thousand were brought into the most holy faith.
