May I suggest another viewpoint...
The 1,260 years began at Mt Sinai.
Observe...
Revelation 12:5
"And she brought forth a man child, who was to rule all nations with a rod of iron: and her child was caught up unto God, and to his throne"
That would be Sarah giving birth to Isaac who represents 'Abraham's Seed' and eventually Christ.
Next...
Revelation 12:6
"And the woman fled into the wilderness, where she hath a place prepared of God, that they should feed her there a thousand two hundred and threescore days"
The above verse refers to Israel fleeing to the Wilderness.
Next...
Revelation 12:15
"And the serpent cast out of his mouth water as a flood after the woman, that he might cause her to be carried away of the flood"
The above verse refers to the parting of the Red Sea account.
Etc. Etc.
It all fits if One is open minded enough to study it all out.
No, that was the true church, basically the believers that were being persecuted that had to flee from the apostate church. Here is a good explanation...

The Woman Symbolizes the Church
Revelation 12 is basically the narrative account of a beautiful, sun-clad woman and her descendants. “And there appeared a great wonder in heaven; a woman clothed with the sun, and the moon under her feet, and upon her head a crown of twelve stars” (Revelation 12:1).
Here we are introduced to one of the most familiar symbols in the Bible. In both the Old and the New Testaments, God represents His people by a woman. As the bridegroom, He is married to the church. Paul wrote to the Corinthians, “I have espoused you to one husband, that I may present you as a chaste virgin to Christ” (2 Corinthians 11:2).
All through the Bible we can follow the record of this symbolism. God said in the Old Testament, “I have likened the daughter of Zion to a comely and delicate woman” (Jeremiah 6:2). And again, “Say unto Zion, Thou art my people” (Isaiah 51:16). The church is called Zion and God compares it with a beautiful woman. In the Old Testament, Israel was the chosen people so often portrayed as being married to God.
In the New Testament, the true Israel of God is no longer a nation but a church composed of Jews and Gentiles who receive Christ as their Savior. Therefore, the woman of Revelation 12 flashes us the picture-story of the church at the time of Christ. The clothing of sunlight typifies the glorious New Covenant of grace, and the twelve stars represent the twelve apostles. The moon under her feet indicates the fading glory of the Old Covenant in the presence of the true Lamb of God....
Persecution of the Church
With no direct access to Jesus, the dragon (Rome) now turned his anger against the followers of Christ, the church: “And when the dragon saw that he was cast unto the earth, he persecuted the woman which brought forth the man child” (Revelation 12:13).
These words provide only a tiny hint of the horror of the violence which broke forth against the apostolic church. Practically all the early disciples and church leaders were martyred for their faith. Cruel pagan emperors turned the sporting arenas and coliseums into theaters of death for those who followed the true gospel.
Soon pagan Rome yielded to papal Rome, and the persecutions continued with even greater force. Millions died under the terrible inquisitions which sought to eradicate all opposition to the papal system. Historians estimate that during the Dark Ages more that fifty million people laid down their lives rather than yield up their Protestant faith.
But let’s follow the tragic story in our prophetic outline. Revelation 12:14 tells us what the true church did as the pressures of persecution built up to a climax: “And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent.”
In order to escape extinction, the faithful Protestant refugees fled back into the Alpine mountains and valleys holding onto the true doctrine delivered by Jesus. Another book of Acts could be written about the heroism of the Waldenses, Huguenots, and Albigenses who refused to surrender their faith during those centuries of fierce oppression. God fought for them, and sometimes the pursuing armies of Rome were cut off by mysterious avalanches and rock slides. At other times the mountain streams were reddened by the blood of those faithful ones who sealed their devotion to the truth with their lives. The Revelation prophecy gives a symbolic picture of the desperate attempts made to wipe out those minority Christians who were now in hiding for their very survival: “And the serpent cast out of his mouth water as a flood after the woman, that he might cause her to be carried away of the flood” (Revelation 12:15).
How long was the true church to remain out of sight in the wilderness? The prophecy declares it would be for “a time, times, and half a time.” How mysterious! What is meant by this strange description of the time period involved? When would it end? The answer is found in verse 6: “And the woman fled into the wilderness, where she hath a place prepared of God, that they should feed her there a thousand two hundred and threescore days.”
Now the picture begins to clear up. One verse says the woman was in the wilderness for 1,260 days and the other verse says she was there for “a time, times, and half a time.” These two periods are equal. This means that a “time” has to be a year in prophetic symbolism, “times” is two years, and “half a time” is half a year. When we add up the one, the two, and the half, we get three and a half years. And that is equal to exactly 1,260 days, using the Bible reckoning of 30 days to the month.
There is one more principle of prophetic interpretation to take into account here. In symbolic Bible prophecy a day always stands for a year. You will find the key for that principle in Ezekiel 4:6: “I have appointed thee each day for a year.” It is laid down elsewhere in these words: “. . . forty days, each day for a year” (Numbers 14:34).
Please note that this applies only to symbolic prophecy, and cannot be read into other portions of the Scripture. A day is used for a year only in the setting of an obvious prophetic context. This places the woman in her wilderness hideaway for the full period of 1,260 literal years.
Our conclusion must be, then, that the true church could not appear in the world until the end of the 1,260 years. Did such a thing happen to the true people of God? How long did the papal power continue to suppress the true doctrines by the exercise of her religio-political authority?
Here is a fascinating point of history. In a.d. 538 a decree by Emperor Justinian went into effect which assigned absolute spiritual preeminence to the church of Rome. Gradually, this religious tyranny drifted into union with civil powers until eventually kings were forced to seek permission from the pope before they could begin to rule. This authority remained in force until the year 1798 when Europe was rocked by the French Revolution. In the subsequent rebellion of the oppressed peasants against the privileged clergy, the pope was captured in 1798. The papal property was confiscated, and the French Directory government decreed that there would be no more Bishop of Rome. The oppressive rule of the papacy ended exactly 1,260 years after it was inaugurated in A.D. 538."...
