>             Project: Apache Airflow
>          Issue Type: Improvement
>          Components: core, scheduler
>    Affects Versions: 1.10.7
>            Reporter: t oo
>            Priority: Minor

> For refactor:
> https://github.com/apache/airflow/blob/master/airflow/models/dag.py#L781 has start_date = (timezone.utcnow() - timedelta(30)).date()
> which then gets used in
> TaskInstance.execution_date >= start_date,
> from what I can tell it is only used by callback functions?
> If dagrun is passed into callback then exact execution_date is already known? 
> looks like it has existed since first commit 5 years ago:
> https://github.com/apache/airflow/blob/1047940ca4363b04044c4963b9c88f7632746407/core/models.py#L760
