#  pandas.DatetimeIndex.inferred_freq  #

DatetimeIndex.  inferred_freq  [ [source]  ](https://github.com/pandas-
dev/pandas/blob/v2.2.2/pandas/core/indexes/datetimelike.py#L523-L526) #

    

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

Returns None if it canâ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'
