我的系统是Hijri格式，如何在乔治亚语类型的类中创建Datetime get set？

import datetime
import hijri_converter

class GeorgianDate:
    def __init__(self, hijri_date):
        self._hijri_date = hijri_date

    @property
    def hijri_date(self):
        return self._hijri_date

    @hijri_date.setter
    def hijri_date(self, hijri_date):
        self._hijri_date = hijri_date

    def to_georgian_date(self):
        georgian_date = hijri_converter.Hijri(hijri_date).to_georgian()
        return georgian_date

import datetime
import hijri_converter

class GeorgianDate:
    def __init__(self, hijri_date):
        self._hijri_date = hijri_date

    @property
    def hijri_date(self):
        return self._hijri_date

    @hijri_date.setter
    def hijri_date(self, hijri_date):
        self._hijri_date = hijri_date

    def to_georgian_date(self):
        georgian_date = hijri_converter.Hijri(self._hijri_date).to_georgian()
        return georgian_date
