# pandas.DatetimeIndex.tz_convert

DatetimeIndex.tz_convert(tz)

  Convert tz-aware Datetime Array/Index from one time zone to another.

  Parameters:
    tzstr, pytz.timezone, dateutil.tz.tzfile, datetime.tzinfo or None

      Time zone for time. Corresponding timestamps would be converted to this time zone of the Datetime Array/Index. A tz of None will convert to UTC and remove the timezone information.

  Returns:
    Array or Index
  Raises:
    TypeError

      If Datetime Array/Index is tz-naive.

  See also

  `DatetimeIndex.tz`

    A timezone that has a variable offset from UTC.

  `DatetimeIndex.tz_localize`

    Localize tz-naive DatetimeIndex to a given time zone, or remove timezone from a tz-aware DatetimeIndex.

  Examples

  With the tz parameter, we can change the DatetimeIndex to other time zones:

      >>> dti = pd.date_range(start='2014-08-01 09:00',
      ...                     freq='h', periods=3, tz='Europe/Berlin')

      >>> dti
      DatetimeIndex(['2014-08-01 09:00:00+02:00',
                     '2014-08-01 10:00:00+02:00',
                     '2014-08-01 11:00:00+02:00'],
                    dtype='datetime64[ns, Europe/Berlin]', freq='h')

      >>> dti.tz_convert('US/Central')
      DatetimeIndex(['2014-08-01 02:00:00-05:00',
                     '2014-08-01 03:00:00-05:00',
                     '2014-08-01 04:00:00-05:00'],
                    dtype='datetime64[ns, US/Central]', freq='h')

  With the `tz=None`, we can remove the timezone (after converting to UTC if necessary):

      >>> dti = pd.date_range(start='2014-08-01 09:00', freq='h',
      ...                     periods=3, tz='Europe/Berlin')

      >>> dti
      DatetimeIndex(['2014-08-01 09:00:00+02:00',
                     '2014-08-01 10:00:00+02:00',
                     '2014-08-01 11:00:00+02:00'],
                      dtype='datetime64[ns, Europe/Berlin]', freq='h')

      >>> dti.tz_convert(None)
      DatetimeIndex(['2014-08-01 07:00:00',
                     '2014-08-01 08:00:00',
                     '2014-08-01 09:00:00'],
                      dtype='datetime64[ns]', freq='h')
