The age beginning after Christ's ascension and continuing on to today. It will end at the time of Christ's Second Coming and Rapture. Only the Father in Heaven knows when that will happen. No books, no Scripture, and no present-day prophets (false or otherwise) can tell us the day of Christ's return.
Answer:
The term "church age" isn't biblical... but is a label devised by men.... like the "ice age" or the "stone age" or the "bronze age"... and other imaginative teachings of men.
"Church" is a word that became the modern English translation of the Holy Spirit-inspired Greek word, "ekklesia" [a calling out, a popular meeting, congregation, cadre].
God has been "calling out" His saints from the beginning, starting with "faithful" Abel [see Hebrews 11:4]. All the great names in what is called the "Old Testament" are God's "church" [called-out-ones] also.
God's "church"... His "saints"... called-out-ones, shall inherit the Kingdom of God [Dan.7:18]. And Jesus tells us that: "...ye shall see Abraham, and Isaac, and Jacob, and all the prophets, in the Kingdom of God, and you yourselves thrust out." (Luke 13:28)
Faithful Stephen, whose first witness and testimony to the Lord was his last, called the ancient Israelites, then recently liberated from Egypt, an "ekklesia"... "congregation" [church]:
"This is he [Moses], that was in the church in the wilderness..." (Acts 7:38).
So, if God's "church" can be said to have an "age"... it would have to span the entirety of man's existence to include all of the "faithful" of God, beginning with Abel.
