Defined in header <chrono>
constexpr std::chrono::year operator ""y(unsigned long long y) noexcept;	(1)	(since C++20)

Forms a std::chrono::year literal representing a year in the proleptic Gregorian calendar.

Parameters

y

-

the year value

Return value

A std::chrono::year initialized from int(y). If y > 32767, the stored value is unspecified.

Possible implementation

constexpr std::chrono::year operator ""y(unsigned long long y) noexcept { return std::chrono::year(int(y)); }

Notes

This operator is declared in the namespace std::literals::chrono_literals, where both literals and chrono_literals are inline namespaces. Access to this operator can be gained with using namespace std::literals, using namespace std::chrono_literals, and using namespace std::literals::chrono_literals.

In addition, within the namespace std::chrono, the directive using namespace literals::chrono_literals; is provided by the standard library, so that if a programmer uses using namespace std::chrono; to gain access to the classes in the chrono library, the corresponding literal operators become visible as well.
