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 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'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 need to develop a web service, that will help the client to do some periodic job, the api will like this
void Dojob(int jobType, string cronExpression);
because the client/user will do anything the want, i just want to know does the cron expression support the situation below:
the job will fire in the following times:
from 9:10am to 10:50am trigger at every 8 minutes, every day.
from 9:00 to 10:00 maybe easier, but i still cannot find the correct cron Expression about 9:10am to 10:50am.
Not sure if you can do this using one cron expression, but you can using two.
eg
0 10,18,26,34,42,50,58 9 1/1 * ? *
0 6,14,22,30,38,46 10 1/1 * ? *
As sgmoore said, you cannot do this using 1 cron expression. You'll have to create 2 triggers each with different cron expressions to get this to work.
The first will be from 9:10 to 9:59 every 8 minutes which looks like this:
0 10-59/8 9 1/1 * ? *
The second will be from 10:00 to 10:50 every 8 minutes which looks like this:
0 0-50/8 10 1/1 * ? *
Just be warned that due to how cron expressions work, this will fire every 8 minutes restarting at the top of every hour, therefore firing at both 9:58 and 10:00 in this scenario
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 * * ?
