also When john wrote revelation he used the 360 day Calender 30 days in every month
1260 day = 3 ½ years
42 months = 3 ½ years
A time times and half time = 3 ½ years.
You don’t need to be a mathematics genius or even to know the old Hebrew Calender
I don't wish to be offensive and I'm not going to argue about it, but you have made assumptions that have now been proven wrong biblically and historically.
1. The 1290 days of Dan 12:11, fulfilled in 688AD by the construction of the Islamic Dome of the Rock.
2 The 42 months of Rev 11:2, fulfilled in 1967AD by the freeing of Jerusalem from Gentile control.
3. The 1260 Days of Rev 11:3, fulfilled in 1948AD by the Jewish people returning to their homeland.
4. The 1260 days of Rev 12:5, fulfilled in 1948AD by the establishment of the new nation of Israel.
5. The Time, Times and Half Time of Dan 7:25, fulfilled in 1948AD by the new nation of Israel.
6. The Time, Times and Half Time of Dan 12:7, fulfilled in 1967AD by the freeing of Jerusalem.

Seven prophecies fulfilled to the year. It is a statistical impossibility for the above seven prophecies to exactly fit Scripture and history to the year, as they do, unless those are the correct interpretations. And my, what doors of understanding those prophecies open for us. Looking back at the rest of the Bible, we now know that Gentile control of the Holy Land is over. We can also identify the Two Witnesses so we now know God has never forgotten the Jews. We further know that the Abomination of Desolation is not an antichrist in our future, but a building that’s been on Mount Moriah for over 1300 years.
And because of those fulfilled prophecies, it appears that most of Revelation is not about events still in our future, but about things that have taken place in our era. These fulfillments of prophecy are real, whether we want to believe them or not, and they strongly impact our traditional ideas of what is yet to come. Prophecies thought to be about a future Seven-Year Tribulation were actually about something else entirely, events that have happened during the Christian era.
