calendar.h ~ calendar ~ day_of_year_type

namespace calendar::day_of_year { typedef /* implementation defined */ day_of_year_type; }

Description

Defines integer type to store the representation of days in a year.

An ISO 8601 valid day_of_year_type must have a value between 1 and 366, in which case it can be safely handled as a yday parameter such as in datetime_type structure, otherwise the program is ill-formed.

Examples

In the following example, we display today's day of year.

#include <iostream>
#include <JLC/JLC.h>
using namespace JLC;
using namespace calendar::day_of_year;

int main(){
    const Date today = Date::now();
    const day_of_year_type yday = today.day_of_year();
    std::cout << today << std::endl;
    std::cout << yday << std::endl;
}
