        :param date_string:
            A string representing date and/or time in a recognizably valid format.
        :type date_string: str

        :param date_formats:
            A list of format strings using directives as given
            `here <https://docs.python.org/2/library/datetime.html#strftime-and-strptime-behavior>`_.
            The parser applies formats one by one, taking into account the detected languages/locales.
        :type date_formats: list

        :param languages:
            A list of language codes, e.g. ['en', 'es', 'zh-Hant'].
            If locales are not given, languages and region are used to construct locales for translation.
        :type languages: list

        :param locales:
            A list of locale codes, e.g. ['fr-PF', 'qu-EC', 'af-NA'].
            The parser uses only these locales to translate date string.
        :type locales: list

        :param region:
            A region code, e.g. 'IN', '001', 'NE'.
            If locales are not given, languages and region are used to construct locales for translation.
        :type region: str

        :param settings:
            Configure customized behavior using settings defined in :mod:`dateparser.conf.Settings`.
        :type settings: dict

        :param detect_languages_function:
            A function for language detection that takes as input a string (the `date_string`) and
            a `confidence_threshold`, and returns a list of detected language codes.
            Note: this function is only used if ``languages`` and ``locales`` are not provided.
        :type detect_languages_function: function

        :return: Returns :class:`datetime <datetime.datetime>` representing parsed date if successful, else returns None
        :rtype: :class:`datetime <datetime.datetime>`.
        :raises:
            ``ValueError``: Unknown Language, ``TypeError``: Languages argument must be a list,
            ``SettingValidationError``: A provided setting is not valid.
