## Class greg_year

boost::gregorian::greg_year — Represent a year (range 1400 - 9999)

## Synopsis

    // In header: <boost/date_time/gregorian/greg_year.hpp>

    class greg_year : public greg_year_rep {
    public:

      // public member functions
      greg_year(value_type);
      BOOST_CXX14_CONSTEXPR operator value_type() const;
    };

## Description

This small class allows for simple conversion an integer value into a year for the gregorian calendar. This currently only allows a range of 1400 to 9999. Both ends of the range are a bit arbitrary at the moment, but they are the limits of current testing of the library. As such they may be increased in the future.

### `greg_year` public member functions

1.     greg_year(value_type year);

2.     BOOST_CXX14_CONSTEXPR operator value_type() const;
