DOC: Incorrect Source Link

[gboeker]

Pandas version checks

• I have checked that the issue still exists on the latest versions of the docs on main here

Location of the documentation

https://pandas.pydata.org/docs/reference/api/pandas.DatetimeIndex.quarter.html

Documentation problem

source link for DatetimeIndex.quarter directs to incorrect code
https://github.com/pandas-dev/pandas/blob/v2.2.2/pandas/core/indexes/extension.py#L67-L75

Suggested fix for documentation

replace with the following link

pandas/pandas/core/arrays/datetimes.py

Lines 1817 to 1845 in 4afc277

	quarter = _field_accessor(
	"quarter",
	"q",
	"""
	The quarter of the date.
	Examples
	--------
	For Series:
	>>> s = pd.Series(["1/1/2020 10:00:00+00:00", "4/1/2020 11:00:00+00:00"])
	>>> s = pd.to_datetime(s)
	>>> s
	0 2020-01-01 10:00:00+00:00
	1 2020-04-01 11:00:00+00:00
	dtype: datetime64[ns, UTC]
	>>> s.dt.quarter
	0 1
	1 2
	dtype: int32
	For DatetimeIndex:
	>>> idx = pd.DatetimeIndex(["1/1/2020 10:00:00+00:00",
	... "2/1/2020 11:00:00+00:00"])
	>>> idx.quarter
	Index([1, 1], dtype='int32')
	""",
	)

i've seen similar issues in pandas.DatetimeIndex.month and pandas.DatetimeIndex.year

Source link for DatetimeIndex.round also looks incorrect:
Should change to:
https://github.com/pandas-dev/pandas/blob/v2.2.2/pandas/core/arrays/datetimelike.py#L1795-L1856

The following also look incorrect:
DatetimeIndex.floor
DatetimeIndex.std
DatetimeIndex.time
DatetimeIndex.timetz

I would love to work on this issue if it looks correct
