Django celery crontab every 30 seconds - is it even possible?

Can crontab django celeryab be launched in 30 seconds DURING SPECIFIC HOURS ?

There are only minutes, hours and days settings.

I have crontab running, but I would like to run it every 30 seconds, unlike every minute.

As an alternative...

Is it possible to turn on the interval for 30 seconds and turn on the interval schedule only for a certain period of the day?

The very first example that they have in the documentation is ......

Example: Run the tasks.add task every 30 seconds.

from datetime import timedelta

CELERYBEAT_SCHEDULE = {
    "runs-every-30-seconds": {
        "task": "tasks.add",
        "schedule": timedelta(seconds=30),
        "args": (16, 16)
    },
}
