# pandas.TimedeltaIndex.inferred_freq

TimedeltaIndex.inferred_freq

  Tries to return a string representing a frequency generated by infer_freq.

  Returns None if it can’t autodetect the frequency.

  Examples

  For DatetimeIndex:

      >>> idx = pd.DatetimeIndex(["2018-01-01", "2018-01-03", "2018-01-05"])
      >>> idx.inferred_freq
      '2D'

  For TimedeltaIndex:

      >>> tdelta_idx = pd.to_timedelta(["0 days", "10 days", "20 days"])
      >>> tdelta_idx
      TimedeltaIndex(['0 days', '10 days', '20 days'],
                     dtype='timedelta64[ns]', freq=None)
      >>> tdelta_idx.inferred_freq
      '10D'
