I am trying to schedule a quartz job in my camel router. The requirement is to have one schedule for Mon-Fri and another for Sat-Sun. I am trying to schedule using single expression.
from("quartz://myTimerName1?cron=0 00 06 ? * MON-FRI")
from("quartz://myTimerName2?cron=0 00 11 ? * SAT-SUN")
Currently I am doing this by starting it as 2 routes. Just wanted to check if it can be achieved in single route.
Thanks

Like i have tried multiple combinations in cron guru but havent found any possible solution.
I have these two expressions to combine
30 10 1 * *
10 12 2-31 * *
You cannot implement this in one cron expression, you have two options to do that:
easy one: create two copy of the dag, each one with its own cron expression
hard one: create a Timetable and register it in an Airflow plugin, then you can use pass it to your dag as timetable argument instead of schedule_interval.
In this timetable, you can implement two methods:
next_dagrun_info: The scheduler uses this to learn the timetable’s regular schedule
infer_manual_data_interval: When a DAG run is manually triggered (from the web UI, for example), the scheduler uses this method to learn about how to reverse-infer the out-of-schedule run’s data interval (not mandatory).
Actually I am trying to schedule an application , which has to be run at
Cron expression to run application job for every end of quarter on 3rd Sunday at 3:30 AM CST
currently am using 0 */10 * ? * * - which runs for every ten minutes.
when I search on online ,this link https://crontab.guru/every-quarter
0 0 1 */3 * this would run for every quarter I guess.
But for my requirement , which I stated above, am not sure actually.
but , i referred some of the previous questions and some trial and error , I reached something like this 30 3 15-21 */3 SUN but am not sure. Please give your thoughts
OK .. for spring scheduler cron expression, below is my best bet
0 30 03 15-21 3,6,9,12 SUN
should work i think. tested partially. since, the above expression will run only on june.
Rewrite of the question:
Using airflow, I would like to schedule a process to run every two hours from 2 till 10 am and a single time at 22:30. The schedule_interval parameter accepts a cron-expression, but it is not possible to define a single cron-expression to achieve the above scheduling. Currently, I did:
dag = DAG(process_name, schedule_interval='30 2,4,6,8,10,12,14,16,18,20,22,23 * * *', default_args=default_args)
But this will execute the process every 30 minutes past the hour, and this every 2 hours from 2 till 23.
Is there a way I can combine two cron-schedules in Airflow?
0 2-10/2 * * *
30 22 * * *
Original question:
I have 2,4,6,10,12,14,16,18,20,22 00 * *
I need to have 23, 30 in my schedule, but I don't want 2-22 to be run at the 30 min interval.
So, I realized, it is not possible!
You can't use two cron expressions for the same DAG (Might change in the future if PR: Add support for multiple cron expressions in schedule_interval is accepted)
Starting Airflow >=2.2.0:
It is possible to get custom time based triggering using custom Timetable by customizing the DAG scheduling to match what you expect.
To do so you need to define the scheduling logic by implementing next_dagrun_info and infer_manual_data_interval functions - Airflow will leverage this logic to schedule your DAG.

Right now i am running my cron job everyday at 3.00PM
0 15 * * *
But I want to run my cron job twice in a day. 10.30AM and 2.30PM
0 30 10 * * *
I believe this command will run at 10.30AM. How should i run it in 2.30PM?
Cron utility is an effective way to schedule a routine background job at a specific time and/or day on an on-going basis.
Linux Crontab Format
MIN HOUR DOM MON DOW CMD
Example::Scheduling a Job For a Specific Time
The basic usage of cron is to execute a job in a specific time as shown below. This will execute the Full backup shell script (full-backup) on 10th June 08:30 AM.
Please note that the time field uses 24 hours format. So, for 8 AM use
8, and for 8 PM use 20.
30 08 10 06 * /home/yourname/full-backup
30 – 30th Minute
08 – 08 AM
10 – 10th Day
06 – 6th Month (June)
*– Every day of the week
In your case, for 2.30PM,
30 14 * * * YOURCMD
30 – 30th Minute
14 – 2PM
*– Every day
*– Every month
*– Every day of the week

From cron manual http://man7.org/linux/man-pages/man5/crontab.5.html:
Lists are allowed. A list is a set of numbers (or ranges) separated
by commas. Examples: "1,2,5,9", "0-4,8-12".
So in this case it would be:
30 10,14 * * *
you can write multiple lines in case of different minutes, for example you want to run at 10:01 AM and 2:30 PM
1 10 * * * php -f /var/www/package/index.php controller function
30 14 * * * php -f /var/www/package/index.php controller function
but the following is the best solution for running cron multiple times in a day as minutes are same, you can mention hours like 10,30 .
30 10,14 * * * php -f /var/www/package/index.php controller function
I am trying to create scheduler with a help of agenda module. I want to do something simple: to run some job every 30 min. For this one I can use agenda.every('30 minutes', 'my task') function. But how can I tell to agenda to do it exactly in 00 or in 30 minutes of every hour? Since I use for deployment heroku that reboots dynos from time to time I can't be sure that heroku won't move my scheduler from 30 minutes to 45 for example.
You can use cron package from npm also - https://www.npmjs.com/package/cron.
It supports cron syntax. As a result you can write schedules like 0,30 * * * * *.
