Revelation 11,12 and 13 describe the same time period as Daniel:
But the court which is without the temple leave out, and measure it not; for it is given unto the Gentiles: and the holy city shall they tread under foot forty and two months.
Revelation 11:2
And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth.
Revelation 11:3
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.
Revelation 12:6
And there was given unto him a mouth speaking great things and blasphemies; and power was given unto him to continue forty and two months.
Revelation 13:5
1260 days divided by 30 days in a Jewish month = 1260 / 30 = 42 Months
42 Months divided by 12 months in a year = 42 / 12 = 3.5 Years
They are all describing the same time period.
