Examples

The following example demonstrates the xtd::date_time::days_in_month method and the xtd::month_of_year enumeration.

#include <xtd/console>
#include <xtd/date_time>
#include <xtd/startup>
 
class program {
public:
  static auto main() {
    auto days_in_july = xtd::date_time::days_in_month(2001, xtd::month_of_year::july);
    xtd::console::write_line(days_in_july);
    
    // days_in_feb gets 28 because the year 1998 was not a leap year.
    auto days_in_feb = xtd::date_time::days_in_month(1998, xtd::month_of_year::february);
    xtd::console::write_line(days_in_feb);
    
    // days_in_feb_leap gets 29 because the year 1996 was a leap year.
    auto days_in_feb_leap = xtd::date_time::days_in_month(1996, xtd::month_of_year::february);
    xtd::console::write_line(days_in_feb_leap);
  }
};
 
startup_(program::main);
 
// This code produces the following output :
//
// 31
// 28
// 29

Remarks

The xtd::month_of_year enumeration represents the month of the year in calendars that have twelve month per year. The value of the constants in this enumeration ranges from xtd::month_of_year::january to xtd::month_of_year::december. If cast to an integer, its value ranges from one (which indicates xtd::month_of_year::january) to twelve (which indicates xtd::month_of_year::december).

This enumeration is useful when it is desirable to have a strongly typed specification of the day of the week. For example, this enumeration is the type of the property value for the xtd::date_time::day_of_week and xtd::date_time_offset::day_of_week properties.

The members of the xtd::month_of_year enumeration are not localized. To return the localized name of the month of the year, call the xtd::date_time::to_string(string) method with either the "j" or "J" format strings. The former format string produces the abbreviated month name; the latter produces the full month name.
