Adds or subtracts 1 from the month value, reducing the result modulo 12 to an integer in the range [1, 12].
1-2) Performs *this += std::chrono::months{1};
3-4) Performs *this -= std::chrono::months{1};

Parameters


(none)

Return value


1,3) a reference to this month after modification
2,4) a copy of the month made before modification
