Return the timezone.

Returns  :

    

datetime.tzinfo, pytz.tzinfo.BaseTZInfo, dateutil.tz.tz.tzfile, or None

    

Returns None when the array is tz-naive.

Examples

For Series:

    
    
    >>> s = pd.Series(["1/1/2020 10:00:00+00:00", "2/1/2020 11:00:00+00:00"])
    >>> s = pd.to_datetime(s)
    >>> s
    0   2020-01-01 10:00:00+00:00
    1   2020-02-01 11:00:00+00:00
    dtype: datetime64[ns, UTC]
    >>> s.dt.tz
    datetime.timezone.utc
    

For DatetimeIndex:

    
    
    >>> idx = pd.DatetimeIndex(["1/1/2020 10:00:00+00:00",
    ...                         "2/1/2020 11:00:00+00:00"])
    >>> idx.tz
    datetime.timezone.utc
