2112 and 2222
The next palindromic years are going to be 2112 and 2222. There is a 100 year difference between the two.
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)
Millennia usually end in zero, so they can't be palindromes. The next palindromic year will be 2112.

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.

The sum of two palindromic numbers is not necessarily a palindromic number. For example, adding the palindromic numbers 121 and 131 gives 252, which is also a palindrome. However, adding 121 and 122 results in 243, which is not a palindrome. Therefore, while some sums of palindromic numbers can be palindromic, it is not a guaranteed outcome.
