boost::gregorian::gregorian_calendar — Gregorian calendar for this implementation, hard work in the base.
// In header: <boost/date_time/gregorian/greg_calendar.hpp> class gregorian_calendar { public: // types typedef greg_weekday day_of_week_type; // Type to hold a weekday (eg: Sunday, Monday,...). typedef greg_day_of_year_rep day_of_year_type; // Counter type from 1 to 366 for gregorian dates. typedef fancy_date_rep date_rep_type; // Internal date representation that handles infinity, not a date. typedef fancy_date_rep date_traits_type; // Date rep implements the traits stuff as well. };
