1335/1290/1260 Days Explained

3.5 Years—Time Period

Until certain "events" take place for all to see, we are always at least 3.5 years away from the start of The Great Tribulation, which starts the countdown to the actual return of Jesus Christ. The Father is in charge of this as per Matthew 24:36—“But of that day and hour no one knows, not even the angels of [a]heaven, but My Father only. Footnote: [a]NU adds nor the Son [blue highlight emphasis added]

Daniel 7:25—He shall speak pompous words against the Most High, Shall persecute[a] the saints of the Most High, And shall intend to change times and law. Then the saints shall be given into his hand For a time and times and half a time. Footnote: [a]Litwear out

Daniel 12:7—Then I heard the man clothed in linen, who was above the waters of the river, when he held up his right hand and his left hand to heaven, and swore by Him who lives forever, that it shall be for a time, times, and half a time; and when the power of the holy people has been completely shattered, all these things shall be finished.

Revelation 12:14—But the woman was given two wings of a great eagle, that she might fly into the wilderness to her place, where she is nourished for a time and times and half a time, from the presence of the serpent.

1335 Days

Daniel 12:12—Blessed is he who waits, and comes to the one thousand three hundred and thirty-five days.

1290 Days

Daniel 12:11—“And from the time that the daily sacrifice is taken away, and the abomination of desolation is set up, there shall be one thousand two hundred and ninety days.

1260 Days

Revelation 11:2-3But leave out the court which is outside the temple, and do not measure it, for it has been given to the Gentiles. And they will tread the holy city underfoot for forty-two months. And I will give power to my two witnesses, and they will prophesy one thousand two hundred and sixty days, clothed in sackcloth.”

Mathematical Explanation of the 1335 Days—using the year 2017 as if it were the year of Christ's Return.

To be clear: Jeaus Christ did NOT return in 2017. Matthew 24:36—“But of that day and hour no one knows, not even the angels of [a]heaven, but My Father only. Footnote: [a]NU adds nor the Son [blue highlight emphasis added]

It follows from Scripture that the "First Resurrection" will be on Pentecost of whatever year the Father decides.


Here begins the mathematical explanation of when the 1335 days would have begun.

Passover can only ever occur on a Monday, Wednesday, Friday, or Sabbath (Saturday). This locks in the first weekly Sabbath of the Feast of Unleavened Bread, AND when Pentecost has to occur that same year. [This locks in the other Holy Days as well.]

10th Sivan


17th Nisan

17+50= 67; 30+29=59; 67-59=8

Using Pentecost of 2017—6063AM/2017AD June 4/Sivan10, 1335 days earlier would have been Tuesday, October 8/Cheshvan 4, 6059AM/2013AD.
