God's Prophetic Calendar (based upon a 360-day year):

There are 2520 days (seven 360-day years) from the day of Barack Obama's election on November 4, 2008 to the day of the 4th Blood Moon on September 28, 2015.

Gregorian Calendar (based upon a 365.25-day year):

There are 7 years (minus 1 day) from September 29, 2008, the day the DOW JONES (DJIA) fell 777 points, (click to see details) to the day of the 4th Blood Moon on September 28, 2015.​

The correlation between these dates was discovered "coincidentally" while researching the meaning of MENE, MENE, TEKEL, UPAHRSIN (The Handwriting on the Wall) from the book of Daniel. [Those words also happen to mean 2520...see Daniel Chapter 5.]

On April 26, 2015, the President mocked Michele Bachmann when she referred to the "End-Times" (see video clip). The contempt he displayed for the Bible and for Bible prophecy in particular (and for those who believe in Bible Prophecy) is reminiscent of King Belshazzar of Ancient Babylon, described in Daniel Chapter 5. Belshazzar was more interested in carousing than defending his own empire and Obama is more preoccupied with promoting his immorality worldwide as he pressures the country of Kenya to support his debauched policies. He naively believes Iran can be trusted, but commits the worst treachery by betraying our only ally in the Middle East, Israel.

President Obama is modeling King Belshazzar of Ancient Babylon and the United States of America is emulating many of the degenerate traits of Ancient Babylon which are detailed in Jeremiah 50 and 51.

A number of Bible teachers have recently been asking, "Is America the daughter of Babylon?"

Ancient Babylon fell on the 16th of the month of Tishri in 539 BC, which also happens to correspond to September 29th, 2015, the day after the 4th Blood Moon.

Did anything take place on September 28, 2015 relating to the United States?

An interesting article entitled, A Decisive Shift In The Power Balance Has Occurred, was written by Paul Craig Roberts (of the Reagan Administration) describing September 28, 2015 as a pivotal day in the global shift in power, not only in the Middle East, but perhaps world-wide.  Our influence, prestige, and admiration is waning across the world.  Our allies don't trust us, and our enemies do not fear us.

Will we look back at September 28, 2015 as a significant day?...only time will tell.
