BaseOffset arithmetic methods (add, sub, etc.) accept a _DatetimeT but a date is a valid parameter value

[gandhis1]

An error will be given if attempting to subtract an offset from a datetime.date

Should be the Union of the two

[Dr-Irv]

Please provide an example that illustrates a type checker showing an error.

from datetime import date
from pandas.tseries.offsets import Day

x = date.today() - Day()

test_case.py:4: error: No overload variant of "sub" of "date" matches argument type "Day"
test_case.py:4: note: Possible overload variants:
test_case.py:4: note: def __sub__(self, timedelta) -> date
