There is no magical 1 Day equals 1,000 Years in the Bible. There is a passage that says to God 1,000 years is as a day, but it also a day is as 1,000 years. It simply means that because God is an infinite being time does not affect Him the way it affects us. I think you are confusing the 1,000 Millenial kingdom with the 7th week described in the book of Daniel. The actual Hebrew states "There are 7 sets of sevens determined for your people." Sometimes a "set of seven" means a week. Sometimes a "set of seven" means seven years. It was incorrectly translated into english as "week" because that is the most common usage of the term. The 7th "set of seven" is the period right before the 1,000 year Millenial Kingdom.
How this is all interpreted practically depends on your theological leanings, but that is generally accepted by biblical scholars as the correct "lingistical" interpretation.

IIPeter 3:8 Is very clear and it is not written in Hebrew
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.
Christ said "TIME" was shortened so Daniel's weeks have been cut short.
Lords Day is a thousand years and the Prophets continually speak to the Lords Day, in that day, etc....
In 2Peter 3, St. Peter is refering to the mockers who say that since the promise of the Lord's day has not been fulfilled yet, that it will not be fulfilled. (2Peter 3:3 "Know this first of all, that in the last days mockers will come with their mockinf, follow after their own lusts, {v.4} and saying, 'Where is the promise of His coming? For ever since the father fell asleep, all continues just as it was from the beginning of creation.'".
It is talking about judment from God for their sin of unbelief. It will come in God's timing. Since He is not tied to our time and space, we should not assume that because we have not seen judment ourselves, that it is any less likely to come. The whole book of 2 Peter is about warning the church against false doctrine and false teachers. The thousand years is a day and vice versa, has not reflection on the actual time to wait for the judgment. It is an idiom designed to convey that God is not bound by time as we are.
Christ said that if God cut short the time to equal 7 years otherwise no life would be left on the earth after the Day of the Lord.
I believe that Daniel is the only book in the Old Testament to assign a time frame to the "Day of the Lord".
I know that there are legitimate disputes surrounding this topic, but there are certain facts that have to be accepted if one takes a serious and reasonable approach to the text of the Bible.
