Represented internally as int64, and which can be boxed to Timestamp objects that are subclasses of datetime and carry metadata. .. versionchanged:: 2.0.0 The various numeric date/time attributes (:attr:`~DatetimeIndex.day`, :attr:`~DatetimeIndex.month`, :attr:`~DatetimeIndex.year` etc.) now have dtype ``int32``. Previously they had dtype ``int64``. Parameters ---------- data : array-like (1-dimensional) Datetime-like data to construct index with. freq : str or pandas offset object, optional One of pandas date offset strings or corresponding objects. The string 'infer' can be passed in order to set the frequency of the index as the inferred frequency upon creation. tz : zoneinfo.ZoneInfo, pytz.timezone, dateutil.tz.tzfile, datetime.tzinfo or str Set the Timezone of the data. ambiguous : 'infer', bool-ndarray, 'NaT', default 'raise' When clocks moved backward due to DST, ambiguous times may arise. For example in Central European Time (UTC+01), when going from 03:00 DST to 02:00 non-DST, 02:30:00 local time occurs both at 00:30:00 UTC and at 01:30:00 UTC. In such a situation, the `ambiguous` parameter dictates how ambiguous times should be handled. - 'infer' will attempt to infer fall dst-transition hours based on order - bool-ndarray where True signifies a DST time, False signifies a non-DST time (note that this flag is only applicable for ambiguous times) - 'NaT' will return NaT where there are ambiguous times - 'raise' will raise a ValueError if there are ambiguous times. dayfirst : bool, default False If True, parse dates in `data` with the day first order. yearfirst : bool, default False If True parse dates in `data` with the year first order. dtype : numpy.dtype or DatetimeTZDtype or str, default None Note that the only NumPy dtype allowed is `datetime64[ns]`. copy : bool, default None Whether to copy input data, only relevant for array, Series, and Index inputs (for other input, e.g. a list, a new array is created anyway). Defaults to True for array input and False for Index/Series. Set to False to avoid copying array input at your own risk (if you know the input data won't be modified elsewhere). Set to True to force copying Series/Index up front. name : label, default None Name to be stored in the index.

Return an Index of formatted strings specified by date_format, which supports the same string format as the python standard library. Details of the string format can be found in `python string format doc `__. Formats supported by the C `strftime` API but not by the python string format doc (such as `"%R"`, `"%r"`) are not officially supported and should be preferably replaced with their supported equivalents (such as `"%H:%M"`, `"%I:%M:%S %p"`). Note that `PeriodIndex` support additional directives, detailed in `Period.strftime`. Parameters ---------- date_format : str Date format string (e.g. "%Y-%m-%d"). Returns ------- ndarray[object] NumPy ndarray of formatted strings. See Also -------- to_datetime : Convert the given argument to datetime. DatetimeIndex.normalize : Return DatetimeIndex with times to midnight. DatetimeIndex.round : Round the DatetimeIndex to the specified freq. DatetimeIndex.floor : Floor the DatetimeIndex to the specified freq. Timestamp.strftime : Format a single Timestamp. Period.strftime : Format a single Period. Examples -------- >>> rng = pd.date_range(pd.Timestamp("2018-03-10 09:00"), periods=3, freq="s") >>> rng.strftime("%B %d, %Y, %r") Index(['March 10, 2018, 09:00:00 AM', 'March 10, 2018, 09:00:01 AM', 'March 10, 2018, 09:00:02 AM'], dtype='str') F)namer4copy)rdrIrrgr4)rb date_formatarrs rDrIzDatetimeIndex.strftimes5Vj!!+..Sty FFFFrNrc|j|}t|||j|jS)aW Convert tz-aware Datetime Array/Index from one time zone to another. Parameters ---------- tz : str, zoneinfo.ZoneInfo, 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 Datetme Array/Index with target `tz`. 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[us, 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[us, 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[us, 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[us]', freq='h') rgrefs)rdrHtyper9rg _references)rbr2rjs rDrHzDatetimeIndex.tz_convertHs@Fj##B''Dzz%%c @P%QQQrNraise ambiguousr) nonexistentr*c|j|||}t|||jS)a Localize tz-naive Datetime Array/Index to tz-aware Datetime Array/Index. This method takes a time zone (tz) naive Datetime Array/Index object and makes this time zone aware. It does not move the time to another time zone. This method can also be used to do the inverse -- to create a time zone unaware object from an aware object. To that end, pass `tz=None`. Parameters ---------- tz : str, zoneinfo.ZoneInfo,, pytz.timezone, dateutil.tz.tzfile, datetime.tzinfo or None Time zone to convert timestamps to. Passing ``None`` will remove the time zone information preserving local time. ambiguous : 'infer', 'NaT', bool array, default 'raise' When clocks moved backward due to DST, ambiguous times may arise. For example in Central European Time (UTC+01), when going from 03:00 DST to 02:00 non-DST, 02:30:00 local time occurs both at 00:30:00 UTC and at 01:30:00 UTC. In such a situation, the `ambiguous` parameter dictates how ambiguous times should be handled. - 'infer' will attempt to infer fall dst-transition hours based on order - bool-ndarray where True signifies a DST time, False signifies a non-DST time (note that this flag is only applicable for ambiguous times) - 'NaT' will return NaT where there are ambiguous times - 'raise' will raise a ValueError if there are ambiguous times. nonexistent : 'shift_forward', 'shift_backward, 'NaT', timedelta, default 'raise' A nonexistent time does not exist in a particular timezone where clocks moved forward due to DST. - 'shift_forward' will shift the nonexistent time forward to the closest existing time - 'shift_backward' will shift the nonexistent time backward to the closest existing time - 'NaT' will return NaT where there are nonexistent times - timedelta objects will shift nonexistent times by the timedelta - 'raise' will raise a ValueError if there are nonexistent times. Returns ------- Same type as self Array/Index converted to the specified time zone. Raises ------ TypeError If the Datetime Array/Index is tz-aware and tz is not None.

Index.slice_indexer, customized to handle time slicing. In addition to functionality provided by Index.slice_indexer, does the following: - if both `start` and `end` are instances of `datetime.time`, it invokes `indexer_between_time` - if `start` and `end` are both either string or None perform value-based selection in non-monotonic cases.

Returns the range of equally spaced time points (where the difference between any two adjacent points is specified by the given frequency) such that they fall in the range `[start, end]` , where the first one and the last one are, resp., the first and last time points in that range that fall on the boundary of ``freq`` (if given as a frequency string) or that are valid for ``freq`` (if given as a :class:`pandas.tseries.offsets.DateOffset`). If ``freq`` is positive, the points satisfy `start <[=] x <[=] end`, and if ``freq`` is negative, the points satisfy `end <[=] x <[=] start`. (If exactly one of ``start``, ``end``, or ``freq`` is *not* specified, this missing parameter can be computed given ``periods``, the number of timesteps in the range. See the note below.) Parameters ---------- start : str or datetime-like, optional Left bound for generating dates. end : str or datetime-like, optional Right bound for generating dates. periods : int, optional Number of periods to generate. freq : str, Timedelta, datetime.timedelta, or DateOffset, default 'D' Frequency strings can have multiples, e.g. '5h'. See :ref:`here ` for a list of frequency aliases. tz : str or tzinfo, optional Time zone name for returning localized DatetimeIndex, for example 'Asia/Hong_Kong'. By default, the resulting DatetimeIndex is timezone-naive unless timezone-aware datetime-likes are passed. normalize : bool, default False Normalize start/end dates to midnight before generating date range. name : Hashable, default None Name of the resulting DatetimeIndex. inclusive : {"both", "neither", "left", "right"}, default "both" Include boundaries; Whether to set each bound as closed or open. unit : {'s', 'ms', 'us', 'ns', None}, default None Specify the desired resolution of the result. If not specified, this is inferred from the 'start', 'end', and 'freq' using the same inference as :class:`Timestamp` taking the highest resolution of the three that are provided. .. versionadded:: 2.0.0 **kwargs For compatibility. Has no effect on the result. Returns ------- DatetimeIndex A DatetimeIndex object of the generated dates. See Also -------- DatetimeIndex : An immutable container for datetimes. timedelta_range : Return a fixed frequency TimedeltaIndex. period_range : Return a fixed frequency PeriodIndex. interval_range : Return a fixed frequency IntervalIndex. Notes ----- Of the four parameters ``start``, ``end``, ``periods``, and ``freq``, a maximum of three can be specified at once. Of the three parameters ``start``, ``end``, and ``periods``, at least two must be specified. If ``freq`` is omitted, the resulting ``DatetimeIndex`` will have ``periods`` linearly spaced elements between ``start`` and ``end`` (closed on both sides). To learn more about the frequency strings, please see :ref:`this link`. Examples -------- **Specifying the values** The next four examples generate the same `DatetimeIndex`, but vary the combination of `start`, `end` and `periods`.
