Question

I’ve looked into PeriodicTask, but the examples only cover making it recur. I’m looking for something more like cron‘s ability to say “execute this task every Monday at 1 a.m.”

Answer 1

The recently released version 1.0.3 supports this now, thanks to Patrick Altman!

Example:

from celery.task.schedules import crontab
from celery.decorators import periodic_task

@periodic_task(run_every=crontab(hour=7, minute=30, day_of_week="mon"))
def every_monday_morning():
    print("This runs every Monday morning at 7:30a.m.")
