    Infer the most likely frequency given the input index.

    Parameters
    ----------
    index : DatetimeIndex, TimedeltaIndex, Series or array-like
      If passed a Series will use the values of the series (NOT THE INDEX).

    Returns
    -------
    str or None
        None if no discernible frequency.

    Raises
    ------
    TypeError
        If the index is not datetime-like.
    ValueError
        If there are fewer than three values.

    Examples
    --------
    >>> idx = pd.date_range(start='2020/12/01', end='2020/12/30', periods=30)
    >>> pd.infer_freq(idx)
