|
Generate a range of dates or timestamps with the spans between dates
|
described by the given `freq` DateOffset.
|
|
Parameters
|
----------
|
start : Timedelta, Timestamp or None
|
First point of produced date range.
|
end : Timedelta, Timestamp or None
|
Last point of produced date range.
|
periods : int or None
|
Number of periods in produced date range.
|
freq : Tick
|
Describes space between dates in produced date range.
|
unit : str, default "ns"
|
The resolution the output is meant to represent.
|
|
Returns
|
-------
|
ndarray[np.int64]
|
Representing the given resolution.

|
Calculate the second endpoint for passing to np.arange, checking
|
to avoid an integer overflow. Catch OverflowError and re-raise
|
as OutOfBoundsDatetime.
|
|
Parameters
|
----------
|
endpoint : int
|
nanosecond timestamp of the known endpoint of the desired range
|
periods : int
|
number of periods in the desired range
|
stride : int
|
nanoseconds between periods in the desired range
|
side : {'start', 'end'}
|
which end of the range `endpoint` refers to
|
|
Returns
|
-------
|
other_end : int
|
|
Raises
