Description

Pandas version checks

• I have checked that this issue has not already been reported.
• I have confirmed this bug exists on the latest version of pandas.
• I have confirmed this bug exists on the main branch of pandas.

Reproducible Example

import pandas as pd

s = pd.Series(pd.to_datetime('2022-02-04')) s = s + pd.DateOffset(1) print(s)

Issue Description

This code snippet produces a series with a date. In Pandas 1.3.5 the date is 2022-02-05. On the other hand in Pandas 1.4.0 the date is abruptly changed to 2022-02-04 which means a API breaking change which is against the Pandas version policy has happened.

Expected Behavior

This code snippet should produce a series with the date is 2022-02-05.

Installed Versions
