COMMENTS

There are exactly 24 such palindromic dates between Jan 1 00 and Dec 31 99 (see b-file for the complete list).

See A210895 for the corresponding dates.

The reference date Mar 1 00 makes sense, since this result in a sequence which is independent from the leap year / non-leap year property of the reference year '00'.
