> The scheduler's DAG run creation logic can be tricky and one is easily confused with the start_date + interval and period end scheduling way of thinking.
> It would ease airflow's usage to add a **next_scheduler_run** property to DAGs so that we can very easily see the (un)famous **period end** after which the scheduler will create a new DAG run for our workflows.
> These patches add such a field to the **dag** table and the DagModel property + scheduler logic to update it when calculated.
> I will attach patches and make a github PR.
