In the western world, one thousand years is comparable to 1000 years, and one year (in the Gregorian schedule) has either 365 or 366 days. Each fourth year is a jump year (for example, 366 days) except if the four-digit year is distinguishable by 100 yet not by 400.

Why Is Millennium So Long?

The word thousand years gets from the Latin word Mille and Annum. Mille implies Thousand, and Annum implies Year. In this manner, the first thousand years are spreading over the years 1–1000 and the second 1001–2000. 

Albeit various well-known festivals denoted the beginning of the year 2000, the 21st century, and the third thousand years, AD started on January 1, 2001.

A sixth-century researcher, Dionysius Exiguous (Dennis the Short), set up the Gregorian schedule in A.D. 532 by fixing A.D. (Anno Domini)1 as the hour of Jesus Christ’s introduction to the world.

 In Dionysius’ time, the idea of counting from 0 had not yet with Europe from the Middle East. Jesus Christ was more probable brought into the world in B.C. 6, yet Dionysius’ framework has held firm consistently. 

Year numbers, then again, are only a method for counting our planet’s unrests. While this is without a doubt a helpful component to depict and structure long time intervals, the Earth’s 1999th transformation around the sun since Christ was born time is actually the same as its 2000th upset.

The year 2000 is exceptional – even though it isn’t the beginning of the 21st century because it is a jump year. Julius Caesar formulated the jump year to address how the earth circles the sun in 352.24219 days.

Since this is not a whole number, the months of the year would gradually drop out of sync with the seasons.


Millennium is a kind of ancient word that carries a lot of debates. There is a different perspective from different people, but there are also some facts that people believe. Jesus Christ was a symbol of its start.

Since Christ was born to process for counting years started with the year 1 (There was no year zero)and this manner, the primary millennium was from the year 1 to the furthest limit of the year 1000, the second millennium from 1001 to the furthest limit of 2000, and the third millennium starting with 2001 and finishing toward the finish of 3000.
