The next palindromic number after 1991 is 2002. A palindromic number reads the same forwards and backwards. In this case, 2002 reads the same whether you read it left to right or right to left.
The smallest non-palindromic number whose square is palindromic is 77. When squared, (77^2 = 5929), which is indeed a palindromic number. The next smallest non-palindromic number, 88, also yields a palindromic square, (88^2 = 7744), but 77 is the smallest such number.

1661 is a palindromic number.

1. 1991 is the only number I think.
1661 is a palindromic number.

A palindrome reads the same both ways. The last palindromic year was 2002. the next palindromic year is 2112. However, the next palindromic date dd/mm/yyyy is 01/02/2010 (01022010)
Example of a palindromic number is 16461.A palindromic number reads the same from both ends, which 16 fails to do.
1991
89 does not have any other number - palindromic or otherwise.
Millennia usually end in zero, so they can't be palindromes. The next palindromic year will be 2112.
