The New Testament (Brit Hadasha) speaks often about this being the last days. If the Apostles lived in the last days and we claim to still be living in the last days, then what in the world are the last days, and how long does the "last days" last?
God did His creating of this world and all that is within it in 6 days. On the 7th day He rested from all of His creative works. In Hebrew eschatology there are 6 days of man and the 7th day is the final day of Messiah and His Kingdom.
The Scriptures record that "a day is as a thousand years and a thousand years as a day".
(2 Peter 3:8, Psalm 90:4) With this in mind there will be 6000 days of man and then 1000 years of a Messianic Kingdom.
Messiah was born and lived during the 4th day, or during the 4000 year period after creation. The 5th and 6th days, 5000 and 6000 years after creation, represent the 5th and the 6th day, or the "last days". After this will come the 7th and final day of this age, or 7000 years after creation, in which Messiah will return and usher in His utopian Kingdom.
We know that there have been over 2000 years since the birth of Messiah. There has not been quite 2000 years since His ministry/crucifixion and resurrection. While we don't know exactly when He will return, we should be able to see that we are living in the 11th hour.
The last days are definitely drawing to a close.
