1) Returns the weekday value stored in*this.

2) Returns the weekday value stored in*this, except that Sunday (stored as0) is interpreted as7 according to ISO 8601.

[edit]Return value

1) The weekday value stored in*this.

2)c_encoding()== 0u? 7u: c_encoding()

[edit]Example

Run this code

#include <chrono>#include <iostream> int main(){std::cout<<"i: C: ISO: Weekday:\n"; for(unsigned i{0}; i!=8;++i){conststd::chrono::weekday w{i};std::cout<< i<<"  "<< w.c_encoding()<<"  "<< w.iso_encoding()<<"    "<< w<<'\n';}}

Output:

i: C: ISO: Weekday:0  0  7    Sun1  1  1    Mon2  2  2    Tue3  3  3    Wed4  4  4    Thu5  5  5    Fri6  6  6    Sat7  0  7    Sun
