We could optimize it more, but we'd end up with something more like some quiz:

        self._add_holiday(
            name,
            self._get_next_workday(
                self._add_holiday(
                    name,
                    self._get_next_workday(
                        self._add_holiday(
                            name, self._get_next_workday(self._next_year_new_years_day, -1)
                        ),
                        -1,
                    ),
                ),
                -1,
            ),
        )
