Folks for saint Peter to have said that 1000 years is like a day for GOD was obviously in support of making sense of the prophetic events to come spoken of in the Book of Revelation.
Quoting: Mr BlackThere is a second supporting verse of the prophetic 1hour in Revelation, one from the Book of GOD
The Covenant of Noah's ark.
2Enoch 33
1 -- And
I appointed the eighth day also, that the eighth day should be the first-created after my work, and that
the first seven revolve in the form of the seventh thousand, and that at the beginning of the eighth thousand there should be a time of not-counting, endless, with neither years nor months nor weeks nor days nor hours.
The first seven days revolving in the form of the seventh thousand, meaning, that every day is like a thousand years. Saint Peter read his scriptures well, and so did saint John knowing that in the last days the Elects who are destined for the 'Rapture' would read them too.
2 Peter
Chapter 3
King James Bible
8 -- But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day.
1000 years (/) 24 hours = 41.666 per hour
