Will 2027 be a year for 70 weeks prophecy fulfilled?

I have placed 1335 days on Tammuz 26 July 31 2027, and worked backward to July 22 2020 as the beginning of tribulation and rapture. Basically, the tribulation is 2520 days plus 45 days which equals to 2565 days. Let's say one day equals to one year. 2565 days becomes 2565 years.

Subtract 2565 years from 2027 the year seventy weeks shall end, we come to 539 BC. 2027 AD ( 2026, there is no 0 in AD) minus 2565 years = 539 BC.

What happens in 539 BC?

Daniel 9:1 In the first year of Darius the son of Ahasuerus, of the seed of the Medes, which was made king over the realm of the Chaldeans; 2 In the first year of his reign I Daniel understood by books the number of the years, whereof the word of the LORD came to Jeremiah the prophet, that he would accomplish seventy years in the desolations of Jerusalem.

539 BC is the year Persia conquered Babylon, and Darius made himself the king of Babylon. 539 BC is also the year Daniel received the seventy weeks prophecy concerning his people Israel. At the end of seventy weeks, Israel shall return to God, and meets their Messiah ( and to anoint the most Holy ).

Daniel 9:24 Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy.

Will it take 2565 years from the time seventy weeks prophecy was given, to have it all fulfilled in 2027?

We shall see.
