I'm using Quartz.net 3.0. How do I create a Cron schedule that fires the first Saturday of every month at 1 am?
If anyone else is checking this post with other variations of this cron schedule use http://www.cronmaker.com. For this question I got 0 0 1 ? 1/1 SAT#1 * which I tested and it looks fine.
I realize this question is a few months old, but in case you haven't already figured it out
"0 1 0 ? * SAT#1" should do the trick.
From the tutorial:
The ‘#’ is used to specify “the nth” XXX weekday of the month.

Is it possible to schedule quartz job for every 3 business days ?
I'm seeing some examples time or specific day or month examples but how to write quartz expression every 3 business days with any month and any year ?
I have tried 0 0 */3 * 1-5 * but got error day-of-week and a day-of-month is not implemented.
Thanks
You cannot specify both a day-of-week (1-5) and a day-of-month (*/3) - one of them must be ?.
How about 0 0 0 ? * MON-FRI/3? Or 0 0 0 ? * MON,THU,TUE,FRI,WED?
EDIT: I tested above - it does not work (the / only seems to work for non-intervals, and the MON,THU,TUE,FRI,WED gets normalized to MON-FRI).
Looking at the source of the next-trigger-day-computation, I am quite confident now that "every 3 business days" is not possible with a single Quartz Scheduler Cron-Expression.
What possibly could work would be a collection of expressions. The "Related" links on the right might give some inspiration.
I need to create a cron trigger that fires at 09:00am, 11:00am, 13:00pm, 15:00pm and 17:00pm, only week days, in Brazil timezone. Can anyone help me please??
I already tried several ways and could not make it work.
Thanks!!
For UTC time:
0 0 9-17/2 ? * MON,TUE,WED,THU,FRI *
if Brazil timezone is -3 UTC, then this should be
0 0 12-20/2 ? * MON,TUE,WED,THU,FRI *
You can use cronmaker utility to generate/check cron expression.
I am having trouble understanding how dates and days work together in a cron job.
Say I have the following command:
0 23 5 1 3 COMMAND
This translates to 23:00, on 5th of January, on Wednesday.
The problem is, that January 5th is a Sunday. How exactly will this command work out? Is the command going to be executed for both January 5th AND for every Wednesday on the month January? Or will it execute just the '5 1' bit?
I am really sorry if it is a really basic question and possibly stupid but to me it really does not make any sense.
Thank you in advance!
Commands are executed by cron when the minute, hour, and month of year fields match the current time, and at least one of the two day fields (day of month, or day of week) match

I currently have a Quartz cron trigger that runs every 10 minutes Monday to Friday with this expression:
0 0/10 * ? * Mon-Fri
I am looking for a way to start the schedule from 1am on Monday and then run it every 10 minutes for the remainder of the week. Is this possible with a single cron expression?
An expression such as 0 0/10 1-23 ? * Mon-Fri would start at 1am but not run between 12 midight and 1am on subequent days, which is not what I need.
I'm not an expert on Quartz, but couldn't you schedule your job twice?
0 0/10 1-23 ? * Mon
0 0/10 * ? * Tue-Fri
The cron expression you told works fine i guess. You can verify it here http://www.cronmaker.com/ by entering your cron expression 0 0/10 * ? * Mon-Fri and check the next schedule.
I am using quartz to schedule my jobs,
I need to execute a job at 2:00am every day and repeat the execution 5 times every 10 minutes, any ideas?
the result should be: 2:00 2:10 2:20 2:30 2:40
Thanks in advance.
I would look at the Quartz CronTrigger, and particularly the usage of / to specify every 'n' minutes/hours whatever.
I think you would need
0 0,10,20,30,40 2 * * ?
to fire at 2am and then 2.10am-2.40am every 10 minutes.
Just specify the schedule times as a cron string for the CronTrigger like this:
0 0,10,20,30,40 2 * * *
Use a CronTrigger with a cron expression that describes the exact times you want it run. For every day at 2:00, 2:10, 2:20, 2:30, 2:40, use:
0 0,10,20,30,40 2 * * ?
A simple solution would be to simply have 5 tasks, one for every 10 minutes.
