# pandas.DatetimeIndex.normalize

DatetimeIndex.normalize()

  Convert times to midnight.

  The time component of the date-time is converted to midnight i.e. 00:00:00. This is useful in cases, when the time does not matter. Length is unaltered. The timezones are unaffected.

  This method is available on Series with datetime values under the `.dt` accessor, and directly on Datetime Array/Index.

  Returns:
    DatetimeArray, DatetimeIndex or Series

      The same type as the original data. Series will have the same name and index. DatetimeIndex will have the same name.

  `floor`

  `ceil`

    Ceil the datetimes to the specified freq.

  `round`

    Round the datetimes to the specified freq.

      >>> idx = pd.date_range(
      ...     start="2014-08-01 10:00", freq="h", periods=3, tz="Asia/Calcutta"
      ... )
      >>> idx
      DatetimeIndex(['2014-08-01 10:00:00+05:30',
                     '2014-08-01 11:00:00+05:30',

                      dtype='datetime64[us, Asia/Calcutta]', freq='h')
      >>> idx.normalize()
      DatetimeIndex(['2014-08-01 00:00:00+05:30',
