# cf.Data.override_calendar

`Data.``override_calendar`(calendar, i=False)

  Override the calendar of the data array elements.

  Not to be confused with using the `change_calendar` method or setting the `d.Units.calendar`. `override_calendar` is different because the new calendar need not be equivalent to the original ones and the data array elements will not be changed to reflect the new units.

  Parameters: | calendar : str The new calendar. i : bool, optional If True then update the data array in place. By default a new data array is created.
  Returns: | out: cf.Data
