+### Calculating Ordinal Dates
+(by [Roland Bock](https://github.com/rbock))
+
+An [ordinal date](https://en.wikipedia.org/wiki/Ordinal_date) consists of a year and a day of year (1st of January being day 1, 31st of December being day 365 or day 366). The year can be obtained directly from year_month_day. And calculating the day is wonderfully easy. In the code below we make us of the fact that year_month_day can deal with invalid dates like the 0th of January:
+
+ int main()
+ {
+ using namespace date;
+
+ const auto time = std::chrono::system_clock::now();
+ const auto daypoint = floor(time);
+ const auto ymd = year_month_day{daypoint};
+
+ // calculating the year and the day of the year
+ const auto year = ymd.year();
+ const auto year_day = daypoint - day_point{year/jan/0};
+
+ std::cout << year << '-' << std::setfill('0') << std::setw(3) << year_day.count() << std::endl;
+
+ // inverse calculation and check
+ assert(ymd == year_month_day{day_point{year/jan/0} + year_day});
+ }
+
