Airflow Calendar: A plugin to transform cron expressions into a visual schedule

[AlvaroCavalcante]

As a Staff Data Engineer, one of my main responsibilities has always been ensuring Airflow's scalability by managing concurrency and overlapping DAG executions.

However, as our environment grew, it became difficult to keep track of every DAG's schedule. With dozens of different cron expressions tailored to meet the needs of multiple teams, maintaining a clear mental map of the workload was almost impossible.

To solve this, I created Airflow Calendar, an open-source plugin inspired by the Google Calendar experience. It organizes all your schedules in a simple, visual time grid and provides a quick look at DAG execution statuses:

You can easily install the plugin in you Airflow environment by running the following command:

pip install airflow-calendar

I’d love to hear your thoughts and feedback!
