Is there any way to implement current plan concept in Airflow..
Example: In Control m jobs will be scheduled as per date example: ODATE : 20200801
But in airflow we are not able to see an option how to schedule the jobs as per every date/calendar..
Is there any best way we can implement..

I'm new to airflow and I'm trying understand what is execution_date means in airflow context. I've read the tutorial page from airflow's documentation which states that
The date specified in this context is an execution_date, which simulates the scheduler running your task or dag at a specific date + time:
I tried to run a task from the tutorial using following command.
airflow test tutorial print_date 2015-06-01
I expected it to print execution_date but the task is printing the actual date on my local system like this.
[2018-05-26 20:36:13,880] {bash_operator.py:101} INFO - Sat May 26 20:36:13 IST 2018
I thought the scheduler will be simulated at a given time. So I'm confused here understanding about execution_date param. Can anyone help me understand this? Thanks.
It's printing the current time in your log because it was actually executed at this time.
The execution date is a DAG run parameter. Tasks can use it to have a date reference different from when the task will actually be executed.
Example: say you're interested in storing currency rates once per day. You want to get rates since 2010. You'll have a task in your DAG to call an API which will return the currency rate for a day. You can create a DAG with a start date of 2010-01-01 with a schedule of once per day. Even if you create it now, in 2018, it will run for every day since the start date and thanks to the execution date you'll have the correct data.
so I have defined a periodic calendar with following periods,
Period A: to factor in start of every month
Period B: to factor in end of every month
Calendar
Now I am trying to schedule the job on every days marked as period A i.e. start of every month by doing the following settings,

Schedule
My Problem
From July month the schedule is getting pre-shifted by 1. Any ideas why?
Also can someone guide me to a detailed documentation on periodic calendars and the values example?
Thanks.
I was not able to reproduce the specific issue you are having. I created the same periodic calendar (Per A = SoM, Per B = EoM) and my job schedule came out as expected.

Schedule
Solution
There is no need to use a periodic calendar for such a simple scheduling requirement. Making use of a periodic calendar incurs maintenance overhead as you need to ensure it is updated every year.
Instead of using a periodic calendar you could simply configure the job as below. This will result in a job that will always execute on the first day of each month, no maintenance required.
I need to put a scheduler in an app that will make a weekly schedule without dates. For example weekly dinner schedule. Or chores schedule, etc. Really just need day of week and time mapped.
Fullcalendar's Scheduler is the perfect format, except it deals with specific dates.
Is there a way I can use it for my use case? Scheduling weekly events without them being tied to specific dates?
I wrote a script to run for an Alfresco rule. but I want the script to run after specific time ( I need the script to run after 1 week). any solution?
I read about Scheduled_Actions , is this feature useful?
Yes, in fact a Scheduled Action is likely your only option for for running something after a certain amount of time has elapsed.
At a high level your solution should look something like:
Your rule sets some aspect/property on the relevant node, say ruleDate, which is the date the original rule ran.
A scheduled action runs every day and detects nodes with a ruleDate 7 days or more in the past.
The scheduled action does whatever changes are required.
The scheduled action removes the ruleDate aspect/property.
Yes it is useful. You need to set up cron job to run scheduled task.

I am looking for a help in converting a IBM Tivoli script to Autosys since we have migrated from Tivoli to AUtosys.
Below is the script in Tivoli -
SCHEDULE SX On RUNCYCLE YEARLY VALIDFROM 02/01/2015 "FREQ=YEARLY;INTERVAL=1;"
UNTIL 0550 +5 DAYS
CARRYFORWARD
...
...
I need to convert this same script so that it can work in Autosys. Not sure, what Tivoli script means and what this Tivoli is doing and how I can convert it in run_calendar in AUtosys script
What about UNTIL and carryforward option ?
Thanks.
This is a TWS Schedule (a set of jobs) that is set to run once a year starting 02/01/2015. It will start on that day at new plan generation and will run until 05:50 am after 5 days. CARRYFORWARD means that this schedule will not disappear at new plan generation that comes everyday.
This is not a script per se, this is a container of jobs. The Autosys calendar must look like a yearly job.
