“execution_date”在 airflow dag 中超过前一天的日期（追赶模式为假）

Question

My airflow dag has catchup as false

Now when I am trying to pass execution_date airflow variable to a script then it it passing the date for previous day.

My airflow timezone is set as America/Los_angelos in the airflow.cfg file (PST TIMEZONE)

Also, it is defintely not a timezone issue. I checked the timings in UTC. The PST dag time is on same UTC day

If you want to pass the current date (ie the date the DAG is triggered) you need to pass data_interval_end . This date represents the end of the data interval that the DAG covers and will be the date that the DAG is triggered.

data_interval_end is a property on the dag_run object

The reason why execution_date is one interval behind is explained here: https://airflow.apache.org/docs/apache-airflow/stable/faq.html#faq-what-does-execution-date-mean

The data_interval is only available in Airflow 2.2+. If you are on a lower version, you will have to work it out yourself using the schedule and the execution date.
