n.b. Other palindromic dates are technically possible if you're willing to mix leading zeroes
e.g. 08.9.1980
...but I'm not counting those.
The 22nd century will have 31 red palindromes, all in December (e.g. 15.12.2151)
plus 21 blue palindromes in January (e.g. 27.1.2172)
and 9 blue palindromes in November (e.g. 4.11.2114)
making 61 in total.
The 23rd century has no red palindromes, because there is no 22nd month.
but it still has 19 blue palindromes in February (e.g. 13.2.2231)
and 9 blue palindromes in December (e.g. 6.12.2216).
It also boasts 81six-digit palindromes
(which only happen in years when the first two digits are the same)
1.1.2211
2.1.2212
...
8.9.2298
9.9.2299
...making a grand total of 109.
The 24th century drops back to 22 palindromes, all blue, all in March. (e.g. 18.3.2381).
Of course all this only applies if you format dates like this
day.month.year
It doesn't work in countries like the USA who do this
month.day.year
Diversion 2
Red palindromes in America are very different.
10.02.2001
01.02.2010
...
08.02.2080
09.02.2090
This century there are only 12 eight-digit US palindromes (always on the second day of the month)
