Comments

There are exactly 214 such palindromic dates between Jan 1 00 and Dec 31 99 (see b-file for the complete list).

See A210891 for the number of days after 'Mar 1 00' to get such a palindromic date.

The definition is different from A210889/A210890 in that the palindrome property is evaluated including the dots.

To get a real date from a term, insert a dot between the second and the third digit from the left and between the second and the third digit from the right.

The first palindromic date in D.M.YY format after 'Jan 01 00' is a(1)=10101 (='10.1.01'= 'Jan, 10 01' = 'Mar 01 00' + A210891(1) days);
The 10th palindromic date in D.M.YY format after 'Jan  01 00' is a(10)=101101 (='10.11.01'= 'Nov 10 01' = 'Mar 01 00' + A210891(10) days);
The 44th palindromic date in D.M.YY format after 'Jan  01 00' is a(44)=21512 (='21.5.12'= 'May 21 12' = 'Mar 01 00' + A210891(44) days);
The last (214th) palindromic date in D.M.YY format after 'Jan 01 00' is a(214)=291192 (='29.11.92'= 'Nov 29 92' = 'Mar 01 00' + A210891(214) days).
