How to delay Dag Run?

[Fthayy]

Airflow 2.5.1

I want to delay the Dag Runs. I'm trying to do it with TimeTable.I delayed the Data Interval Start and Data Interval End but dag worked before them. What I am doing wrong? I found the #28157 but I couldn't understand exactly.

I couldn't understand what you want to do - it's confuxing what you are asking for

Example explaining it in details and rarther than telling "I used timetable to solve it" showing what you tried to do might help in explaining your point more clearly.

BTW. The more time you spend on clearly describing your problem the more likely it is that someone will want to help you.

Appreciate for your feedback.

from datetime import timedelta
from pendulum import UTC, DateTime
from airflow.plugins_manager import AirflowPlugin
from airflow.timetables.base import DagRunInfo, DataInterval, TimeRestriction, Timetable
from datetime import datetime

class AfterWorkdayTimetable(Timetable):
    def infer_manual_data_interval(self, run_after: DateTime) -> DataInterval:
        start = datetime.now().replace(tzinfo=UTC)
        return DataInterval(start=start+timedelta(days=6), end=(start + timedelta(days=7)))
    def next_dagrun_info(self,*,last_automated_data_interval: DataInterval | None,restriction: TimeRestriction,) -> DagRunInfo | None:
        return None  
class WorkdayTimetablePlugin(AirflowPlugin):
    name = "workday_timetable_plugin"
    timetables = [AfterWorkdayTimetable]

my goal here was to assign manually triggered dags directly to 6 days ahead. Data Interval Start and End updated as you can see in screenshot but dag didn't delayed.

I still don't know wha tyou want to achieve. If you want to trigger dags manually and let them start 6 days later this is not possible. You can trigger a dag and let it wait with the sensor for 6 days using Timedelta sensor as part of the dag, but you cannot trigger dag and way for 6 days. You can write an external service tha twill run trigger API call in 6 days if you want.

Thanks again for the answer. I thought it might be possible, I'll try to do it a different way
