Millennia usually end in zero, so they can't be palindromes. The next palindromic year will be 2112.
The next binary palindromic year after 2023 is 2112. In binary, 2112 is represented as 10000111000, which reads the same forwards and backwards, making it a palindrome. The next few binary palindromic years after 2112 are 2222 (10001010110) and 2332 (100100100100).
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 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)
