COMMENTS
For February, the number of days will be 28 only, as the year cannot be a leap year if MMDDYY is to be a prime number.
The sequence is finite, with 27 terms. The largest term is a(27)=91019.
EXAMPLE
a(1)=10301 is palindromic prime and represents a date in MMDDYY format as 010301.
MATHEMATICA
palindromicQ[n_] := TrueQ[IntegerDigits[n] == Reverse[IntegerDigits[n]]]; t = {}; Do[If[m < 8, If[OddQ[m], b = 31, If[m == 2, b = 28, b = 30]], If[OddQ[m], b = 30, b = 31]]; Do[a = 100 d + y + 10000 m; If[PrimeQ[a] && palindromicQ[a], AppendTo[t, a]], {d, 1, b}], {m, 1,
12}, {y, 1, 99}]; Union[t]
