Years of the Beast?

The number 666 is characterized as the Number of the Beast.

I found this interesting as the YEAR 666 had no significantly bad effect on the earth (as far as history is concerned).
Yet the number is related to years now:1

The year 1666 contained the Bubonic Plague that killed 10,000 people. There was also the "Great Fire" which destroyed the better part of London. The horrible events of the year were blamed on the year's date containing the "Number of the Beast."

Y2K- the new millenium was supposed to kill us all. The year 2000 was supposed to be the end of the world. One of the reasons this was expected? 2000 divided by 3 is 666.666666666666.... Endless "Number of the Beast."

Looks like Satanic fear is no more than irrational fear.
Yes Evil exists, no a number does not define the essense of Evil.
Just found it interesting.
