Triggering past execution date through the Airflow UI

Is there a way to trigger a DAG run in the Airflow UI with a custom execution date specified also through the UI?

No there isn’t. If you trigger a DAG run manually via the UI, its execution date will always be the moment you click the button.

Hi @kevinc! Correction here that you CAN trigger a DAG run in the past and specify an execution date via the Airflow Web UI on Airflow versions 1.10.3+ (on Astronomer Cloud).

You should see something like this:


If you’re running vanilla Airflow, keep the following bugs native to Airflow and specific to this feature in mind:

Upgrading Versions

To upgrade to 1.10.3 on Astronomer, throw the following in your Dockerfile:

FROM astronomerinc/ap-airflow:0.9.2-1.10.3-onbuild
