I have a quick question please, i should convert some Quartz Scheduler to unix machine cron.
The Quartz Scheduler is 0 30 11-18/22 * * ? and when i put it in the site : http://www.cronmaker.com/ it shows me that the cron is running every 11h30 of every day.
So for me 0 30 11-18/22 * * is equals to 0 30 11 * * , is this correct ?
Thank you
For every day run at 11:30 you should rewrite the above Quartz Scheduler like:
30 11 * * * /path/to/the/job

I need to schedule a job in databricks that should run at 6am, 6.15, 6.30, 6.45, 7, 7.15, 7.30, 7.45 and 8am every day.
I am using below expression however it is not running at 8am. Is there anyway we can achieve this?
0 0,15,30,45 06,07 ? * *
This is expected behaviour from cron expression. As per your requirement, you need to write separate cron expression for the 08:00 as follows:
Note that some scheduling requirements are too complicated to express
with a single trigger - such as “every 5 minutes between 9:00 am and
10:00 am, and every 20 minutes between 1:00 pm and 10:00 pm”. The
solution in this scenario is to simply create two triggers, and
register both of them to run the same job.
This will run from 6.00 until 7.45, every 15 minutes:
* 0/15 06-07 * * *
If you want it to run until 08:00 then you have to create two triggers and register both if them to run the same job.
* 0/15 06-07 * * *
* 0 08 * * *
Reference: Databricks uses Quartz Cron triggers. Databricks – Cron Triggers
Hope this helps.
Run twice a day at 10:00 and 18:00
**0 0 10,18/12 * * ?**

I'm trying to write a Quartz task that runs on a cron schedule of every 10 minutes between 8am and 4:30pm.
If It was just between 8am and 4pm I would use
s m h dom M dow
0 */10 8-16 ? * MON-FRI
But I need it to run until 4:30 not just 4...
How can I do this?
I think it is impossible to express such requirement in one cron schedule . I would create two cron schedules instead :
0 */10 8-15 ? * MON-FRI (Run from 8:00am to 3:50pm every 10 minutes)
0 0,10,20,30 16 ? * MON-FRI (Run at 4:00pm , 4:10pm , 4:20pm , 4:30pm)
In this particular case you are probably better off using a DailyTimeIntervalTrigger rather than a CronTrigger. Here is a screenshot from QuartzDesk (our Quartz management and monitoring GUI) that shows you an example of a DailyTimeIntervalTrigger with attributes that meet your scheduling requirements:
I'm using Quartz.net to set up a scheduler that send out email everyday at 15.59 o'clock.
And this what I used:
0 59 15 * * ?
but it never fired.
To find out whether my database consists data that will fire the scheduler, I used
0 0/1 * * * ?
that will fire every minute, and it works just fine.
Is there anything wrong with my cron for daily job?
Your cron expression should be : 0 59 15 1/1 * ? *.
This will run your cron job everyday at 15:59. Visit cronmaker to generate more such cron expressions.
I wasn't sure how to schedule a job to run from 10 PM to 7 AM (the next day). I was thinking if something like below would work
0 22-8 * * *
Thanks
I want a cron job (or a combination of 2 jobs) which fires at 00:00, 01:30, 03:00 and so on for all day. What can be the most succinct way to write the expression?
you need to split it into 2 jobs since it is an odd frequency
0 0-21/3 * * * command
30 1-22/3 * * * command
Use following cron expression to configure your cron trigger
0 0/30 0,23 * * ?
