NAME¶

std::chrono::weekday_last::weekday_last - std::chrono::weekday_last::weekday_last

Synopsis¶

constexpr explicit weekday_last( const std::chrono::weekday& wd ) (since C++20)
noexcept;

Constructs a weekday_last object storing the weekday wd.

Notes¶

A more convenient way to construct a weekday_last is with weekday's operator[],
i.e., wd[std::chrono::last].

Example¶

// Run this code

#include <chrono>
#include <iostream>
using namespace std::chrono;

int main()
{
const year_month_day ymd{floor<days>(system_clock::now())};
const weekday_last wdl{Sunday[last]}; // A last Sunday of a month
const year_month_day last_sun{ymd.year() / ymd.month() / wdl};

std::cout << "The last Sunday of current month falls on "
<< (int)last_sun.year() << '/'
<< (unsigned)last_sun.month() << '/'
<< (unsigned)last_sun.day() << '\n';
}

Possible output:¶

The last Sunday of current month falls on 2021/9/26
