 """ Uses the count for each day in the date range to recalculate the counters for the associated weeks and months for the ``metric`` for ``unique_identifier``. Useful for updating the counters for week and month after using set_metric_by_day. The redis backend supports lists for both ``unique_identifier`` and ``metric`` allowing for the setting of multiple metrics for multiple unique_identifiers efficiently. Not all backends may support this. :param unique_identifier: Unique string indetifying the object this metric is for :param metric: A unique name for the metric you want to track :param start_date: Date syncing starts :param end_date: Date syncing end """
