We are using Azure Scheduler API to create scheduling job on Azure Scheduler. We got the new request to create a recurring job that happens at the FIRST WORKING day of every month.
Normally it will be on the 1st day of the month. But if the 1st of the month is Saturday, the first working day will be 3rd (Monday). Or, the 1st day of the month is Sunday, the first working day will be 2nd (Monday). Like the table below:
Is this possible in Azure Scheduler? I know if it's possible with cron job like this link:
http://www.switchplane.com/blog/how-to-run-a-cron-job-on-the-first-weekday-of-the-month/
I just had a quick try at this in Azure Portal and while it seems possible to schedule a task on 1st Monday of every month, I don't think it's possible to say 1st Working Day of every month because Azure Scheduler has no idea what the 1st working day for you would be (it could be a Tuesday if you have a holiday on 1st Monday of the month).

Is it possible to create an expression for quartz scheduler in java which runs the job every 15 minutes but should skip the job runs from Saturday night 9PM to Sunday morning 6AM? So it will be like the job will run all 7 days a week every 15 minutes but should not run from Saturday 9PM to Sunday 6AM (for some maintenance activity at that time).
You can use a Quartz Calendar to exclude certain days and/or time periods. To support your use-case, you have two choices:
Implement a custom calendar by implementing the org.quartz.Calendar or extending org.quartz.BaseCalendar. Internally your custom calendar can use two CronCalendar implementations described below.
Use two "chained" CronCalendars. By chaining, I mean using one calendar as the base calendar of the other calendar. The first calendar will exclude Saturdays 9pm to midnight, the second will exclude Sundays 00am to 6am. These are the cron expression used by these two calendars:
21-23 ? * SAT
00-05 ? * SUN
Here are a few examples showing how to use calendars in your code:

I wish to schedule a airflow job for specific set of dates every month, for example 11th and last day of every month and used the below scheduler expression
25 14 11,L * * # At 2:45 pm on 11th and last day of every month
When I validated the above in https://crontab.guru/ and http://cron.schlitt.info/ i was told the expression as invalid.
Is it possible to schedule together for a known and a unknown (here last) day of every month? If not is there any other way to achieve this?
maybe your cron does not support the "L" flag. you can refer to this CRON job to run on the last day of the month
I have a Azure data factory pipeline that load data of every working day(Run every working day). I want to trigger my pipeline every working day (Mon-Fry) between working hour(9am to 6pm) and hourly.
It should run as daily at 9am then 10am then 11am--------at 6pm.
I have tried tumbling window trigger but I think it does not support time period for trigger interval
In your trigger, you can select a recurrence of one week, then select the working days and then the hours you are interested in.
The recurrence patterns in ADF and Logic Apps don't directly support this combination of requirements. You are certainly welcome to attempt this in an ADF pipeline, but I find Logic Apps to be much easier for this sort of action. Below is an example of how you might configure it:
Create a Logic App with a Recurrence Trigger
In the Trigger, change the Frequency to Day and specify the hours and timezone:
Calculate the day of the week
Us the following expression (change to the appropriate timezone) to extract the day of the week into a variable:
dayOfWeek(convertFromUtc(utcNow(), 'Eastern Standard Time'))
This will return an integer where 0 = Sunday, 1 = Monday, etc.
Add condition based on the day of the week
Use the dayOfWeek integer variable to determine which days to act (or ignore). In this example, I'm exceluding days 0 (Sunday) and 6 (Saturday):
Execute the data factory
In the True condition, execute your data factory (do nothing in the False condition):
I am working on Quartz Scheduler where need to trigger my job on basis of monthly where user can select desired month date from which he want to make it run for every month on that particular date. lets say- I want to schedule quartz job from August 20,2015 which should run every month on 20th, but it should not start by today,must be start on August 20,2015 onward. what would be the cron expression for this?
I have tried a lot to find out the matching thread but did not worked for me.
like if i have to make for every month which start on 20 May 2015 and repeat every 20th date of month the cron expression would be [0 0 12 20 1/1 ? *].for this requirement lot of things available around and works nicely. but how to schedule Quartz which must fire on particular date and repeat onward for every month on that particular date and time?
Please help me out.any link or any guideline would be appreciable.
I was trying to use CRON Maker in my project. I need to do UI based scheduling using CRON Makers. Example site Click here. In my UI, there are some schedules where the user can select any kind. Below are some possibilities.
One Time ( Start date, Time)
Daily ( Start date & Time, Recur Every --- days (Say: -5- days)
Weekly ( Start date & Time, Recur Every --- Weeks on Sun, Mon, Tue (Say: -2- weeks).
Monthly ( Start date & Time, Date (1-31), Month (1-12).
I have done the CRON expression for Monthly schedule. I dont know how to make the CRON expression for the rest of the cases. Please help me for this.
Thanks,
You can below CRON expression generators:
https://github.com/onterumahendra/CronScheduler
https://github.com/onterumahendra/CronScheduler-Foundation
These are well suited if you are using Quartz Scheduler in the back-end. It generates the CRON expressions and populate the CRON expressions in UI as well.
Cron syntax does not support weeks (or any similar construct such as day of year). There is a day of month field, with which one could approximate the n-weekly behaviour.
For the days directive you can use the second field (day of week).
