COMMENTS

There are exactly 322 such palindromic dates between Mar 1 00 and Dec 31 99 (see bfile for the complete list).
See A210890 for the corresponding dates.
The definition is different from A210891 in that the dates are considered as numbers.
The reference date Mar 1 00 makes sense, since this definition results in a sequence which is independent from the leap year / nonleap year property of the reference year '00'.
