Addition/subtraction of integers and integer-arrays with Timestamp is no longer supported. Instead of adding/subtracting `n`, use `n * obj.freq` code example

Example: Addition/subtraction of integers and integer-arrays with DatetimeArray is no longer supported

end_date = (date+timedelta(days=4)).strftime("%Y-%m-%d")
# ...
date = date+timedelta(days=3)
