From cppreference.com
constexpr bool ok() const noexcept; |
(since C++20) | |
Determines whether this month_day
stores a valid month-day combination.
The combination is valid if month() represents a valid month (month().ok() == true), unsigned{day()} >= 1, and unsigned{day()} <= D, where D is the number of days in the month represented by month()
. The number of days in February is considered to be 29.
Return value
true if the month and day combination is valid, otherwise false.
