# pandas.DatetimeIndex.strftime

DatetimeIndex.strftime(date_format)

  Convert to Index using specified date_format.

  Return an Index of formatted strings specified by date_format, which supports the same string format as the python standard library. Details of the string format can be found in python string format doc.

  Formats supported by the C strftime API but not by the python string format doc (such as “%R”, “%r”) are not officially supported and should be preferably replaced with their supported equivalents (such as “%H:%M”, “%I:%M:%S %p”). Note that PeriodIndex support additional directives, detailed in Period.strftime.

  Parameters:
    date_format str

      Date format string (e.g. “%Y-%m-%d”).

  Returns:
    ndarray[object]

      NumPy ndarray of formatted strings.
