The 2060 date is a date picked by Isaac Newton...
And I heard the man clothed in linen, which was upon the waters of the river, when he held up his right hand and his left hand unto heaven, and sware by him that liveth for ever that it shall be for a time, times, and an half.
Daniel 12:7
From a folio cataloged as Yahuda MS 7.3g, f. 13v:
"So then the time times & half a time are 42 months or 1260 days or three years & an half, reckoning twelve months to a year & 30 days to a month as was done in the Calendar of the primitive year. And the days of short lived Beasts being put for the years of lived kingdoms, the period of 1260 days, if dated from the complete conquest of the three kings A.C. 800, will end A.C. 2060." - Isaac Newton
As Charlemagne was crowned king on December 25, 800 by Pope Leo the III so the day of Christ's coming will be on Christmas Day, 2060. If the rapture of the saints (
1 Thessalonians 4:16-17) occurs seven years before the time of Christs coming the date of the rapture 12.25 2053. However
Isaac Newton notes
It may end later, but I see no reason for its ending sooner. This I mention not to assert when the time of the end shall be, but to put a stop to the rash conjectures of fancifull men who are frequently predicting the time of the end, & by doing so bring the sacred prophesies into discredit as often as their predictions fail. Christ comes as a thief in the night, & it is not for us to know the times & seasons which God hath put into his own breast." - Isaac Newton
