    :param int|str day: day of month (1-31)
    :param int|str week: ISO week (1-53)

    :param int|str minute: minute (0-59)
    :param int|str second: second (0-59)
    :param datetime|str start_date: earliest possible date/time to trigger on (inclusive)
    :param datetime|str end_date: latest possible date/time to trigger on (inclusive)
    :param datetime.tzinfo|str timezone: time zone to use for the date/time calculations (defaults
        to scheduler timezone)
    :param int|None jitter: delay the job execution by ``jitter`` seconds at most
