You can put this solution on YOUR website! The year 1991 was thhe last palindrome year of the second millennium. The year 2002 is the first palindrome year of the third millennium. Including 2002, how many palindrome years will there be, altogether, in the third millennium?
Since all years begin with 2, every palindrome year must also end with 2 and the 2nd and 3rd digits must be the same. So
2002, 2112, 2222, 2332, 2442, 2552, 2662, 2772, 2882, 2992.
That's 10.
