>>> import pandas as pd
>>> idx = pd.DatetimeIndex(["1/1/2020 10:00:00+00:00", "2/1/2020 11:00:00+00:00"])
>>> idx.week
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'DatetimeIndex' object has no attribute 'week'
>>> idx.weekday # sanity check
Index([2, 5], dtype='int32')
