pandas.DatetimeIndex

class pandas.DatetimeIndex[source]

Immutable ndarray of datetime64 data, represented internally as int64, and which can be boxed to Timestamp objects that are subclasses of datetime and carry metadata such as frequency information.

Parameters:

data : array-like (1-dimensional), optional Optional datetime-like data to construct index with copy : bool Make a copy of input ndarray freq : string or pandas offset object, optional One of pandas date offset strings or corresponding objects start : starting value, datetime-like, optional If data is None, start is used as the start point in generating regular timestamp data. periods : int, optional, > 0 Number of periods to generate, if generating index. Takes precedence over end argument end : end time, datetime-like, optional If periods is none, generated index will extend to first conforming time on or just past end argument closed : string or None, default None Make the interval closed with respect to the given frequency to the ‘left’, ‘right’, or both sides (None) tz : pytz.timezone or dateutil.tz.tzfile ambiguous : ‘infer’, bool-ndarray, ‘NaT’, default ‘raise’ ‘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 an AmbiguousTimeError if there are ambiguous times infer_dst : boolean, default False (DEPRECATED) Attempt to infer fall dst-transition hours based on order name : object Name to be stored in the index To learn more about the frequency strings, please see `this link <http://pandas.pydata.org/pandas-docs/stable/timeseries.html#offset-aliases>`__.
