Aaron Dossett created AIRFLOW-4740:
--------------------------------------
Summary: default args end_date should be as permissive as
start_date
Key: AIRFLOW-4740
URL: https://issues.apache.org/jira/browse/AIRFLOW-4740
Project: Apache Airflow
Issue Type: Improvement
Components: DAG, models
Affects Versions: 1.10.3
Reporter: Aaron Dossett
A dag will accept, in its default_args, a `start_date` as simple as
`2019-06-01`. If it detects a string, it converts to a richer type ([code
reference|[https://github.com/apache/airflow/blob/master/airflow/models/dag.py#L217-L221]]).
However, it will not accept a similar string for `end_date` instead an
exception like this is thrown:
{code:java}

AttributeError: 'str' object has no attribute 'utcoffset'{code}
That's a very confusing user experience. `end_date` should be as permissive as
`start_date`
