Waits until the first specified day of the week. For example, if the execution day of the task is ‘2018-12-22’ (Saturday) and you pass ‘FRIDAY’, the task will wait until next Friday.

Example (with single day):

weekend_check = DayOfWeekSensor(
    task_id='weekend_check',
    week_day='Saturday',
    use_task_execution_day=True,
    dag=dag)

Example (with multiple day using set):

weekend_check = DayOfWeekSensor(
    task_id='weekend_check',
    week_day={'Saturday', 'Sunday'},
    use_task_execution_day=True,
    dag=dag)

Example (with WeekDay enum):

# import WeekDay Enum
from airflow.contrib.utils.weekday import WeekDay

weekend_check = DayOfWeekSensor(
    task_id='weekend_check',
    week_day={WeekDay.SATURDAY, WeekDay.SUNDAY},
    use_task_execution_day=True,
    dag=dag)
