Usage Samples
=================

.. code:: python

    from cnyear import Cnyear

    # get the Common Era for a Chinese regnal year
    year_obj1 = Cnyear('清康熙十二年')
    year_obj1.cny2y() # return a tuple (1673, None, True) which means (first year, last year, validity)
    year_obj1.y2cny(dig=True) # 清康熙12年

    # get a span of time
    year_obj2 = Cnyear('明正統間')
    year_obj2.cny2y() # (1436, 1449, True)

    # correct the wrong regnal year
    year_obj3 = Cnyear('清咸豐十二年')
    year_obj3.cny2y() # (1862, None, False)
    year_obj3.y2cny() # 清同治元年

    # get the Chinese regnal year for a Common Era
    Cnyear('明崇禎十八年').y2cny(ldefaultdy=['清','南明']) # 清順治二年
    Cnyear('明崇禎十八年').y2cny(ldefaultdy=['南明','清']) # 南明弘光元年


Other Features

#. Convert Chinese digit numbers into Arabic digit numbers in a year and vice versa.
#. Get each component in an expression of year.

#. To support sexagenary cycle 干支.
#. To support operand like minus and plus between years.
