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.

I have a case in which I'm migrating some tasks from Windows to a platform and we are using cron expressions to replace the Windows Scheduler.
Today we have something in Windows like At 10:20 AM every weekday, every 10 minutes for 9 hours. I'm trying to replace it with chron but I couldn't achieve it so far.
The closest I got is 0 20/10 10-19 * * MON-FRI. The thing is on this cron, it won't execute at 11:00, 12:00 and so on. We have a specific case in which we don't want it to execute at 10:00 AM.
The only option I found is to execute at 10:00AM and put some condition to validate it. Is it possible to achieve this result with only chron?
Thanks!
You can do it with cron, but you'll need to break it up into two schedules.
20/10 10 * * MON-FRI
and
*/10 11-19 * * MON-FRI
Btw, if this is cron on unix, there is no field for seconds.
We need to produce Azure CRON Expression to start job at certain date between a start and end time at intervals of hours or minutes.
So say if I want the job to run every 30 mins starting from 7:30 AM to 1:30 PM everyday, my expression should go like below?
0 30/30 7-13 * * *
And to run every 2 hours starting from 7:30 AM to 1:30 PM everyday, my my expression should go like below?
0 30 7-13/2 * * *
Is it possible to achieve these with Azure CRON at all? If not what's my alternative?
The CRON Expressions are not Azure specific but CRON specific.
First you need to get deep into the cron and understand how it works and what does the cron expression mean here. Then you can use tools like CRONTab Guru here to get to your expression.
To get to something that might be the one you search for:
0,30 7-13 * * *
This expression is read:
“At minute 0 and 30 past every hour from 7 through 13.”
Which is basically every 30 minutes starting at 07:00 and ending at 13:30.
You can give yourself a try with the CronTab Guru and find the best suiting formula for you.
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
java - Spring, i want to crate cron expression to run every after 2 hours only on Wednesday till day end
0 0 0/2 * * WED *
mean cron should trigger every wednessday only for these times 2am, 4am, 6am, 8am,10am, 12pm, 2pm,4pm, 6pm, 8pm, 10pm, 12pm
i don't have time long to wait and test can some one please confirm is it correct ?
Even though it is way to late i like to answer the question for other users.
Your CronExpression is invalid. You can check this here or here. The problem is: You cannot specify a day_of_month AND a day_of_week.
Cause you are setting a day_of_week you should skip day_of_month with a "?". Solution should be: 0 0 0/2 ? * WED *
i want a cron expression for a schedule which runs for every 2hr 10 min and output am expecting is
2:00
4:10
6:20
i tried 0 0/2 0/2 * * ? for that and the output was like this

Thanks in advance..
I too had searched a lot previous to run a cron for every (> 60 ) minutes, but was not able to find any solution.
Best way to implement the solution to your problem, is to write your own script that would check the script's last run which you can handle in any way (check timestamp, log the last run somewhere, etc) and would run the required job if only the time conditions are met.
Then put a cron to call this wrapper script every 10 mins (in your case), as this would ensure, it would get checked for each of the time you would have expected the original final job to run.
Hope this helps.
