How can I configure a CronString for Quartz.Net job scheduler for the following job:
Job should run on BiWeekly on Monday at 12:00 AM. i.e. it should run on every Monday but skipping one week in between.
Example:
1st Run => 19-Nov-2012 [Monday] 12:00 AM
2nd Run => 03-Dec-2012 [Monday] 12:00 AM
3rd Run => 17-Dec-2012 [Monday] 12:00 AM
Actually what you might be looking for is CalenderIntervalTrigger, which is capable to do this easily.
var trigger = TriggerBuilder.Create()
.StartAt(new DateTime(2012, 11, 19, 12, 0, 0).ToUniversalTime())
.WithCalendarIntervalSchedule(x => x.WithIntervalInWeeks(2))
.Build();
A "cron expresssion" can be created as follows for any frequency of the week.
int repeatInterval = 2;
int weeklyInterval = repeatInterval*7;
String cronExp="0 0 12 1/ " +weeklyInterval " * ? *";
Creates a cron expression which repeats bi-weekly at 12.
Hope this helps.

I am trying to schedule a jenkins job (timer) to start my Azure VMs back up on the third sunday of every month at 6AM.
I haven't been able to find any resource on this.
From Configure job, You can use Build Periodically option
under Build Trigger section and in the Schedule text field add the expression: 0 0 1 * *
The above expression will schedule a build of the job to run on 1st day of every month. For example, Would last have run at Monday, October 1, 2018 12:00:55 AM EDT; would next run at Thursday, November 1, 2018 12:00:55 AM EDT and so on. To create your own cron based upon your requirement you can use https://crontab.guru/.
I have to schedule a Jenkins job which runs every Day of the week, every Month in a year , every Day in a month but after a specific date.
I have used the below cron expression but it will trigger the job only on 1:00 pm for sept month only.
0 13 * 8 *
I need to schedule it from Sept,01,2018 onward everyday at 1:00pm.
If You want to trigger in future use: Schedule Build Plugin
0 0 13 1 1/1 ? *

Does Jenkins Build Periodically support having 2 different schedules for a job at the same time?
H 22 * 7-12 1-5
H 20 20 1-6 *
The above is just an example. What it intends to do is,
H 22 * 7-12 1-5 : Run the job for last 6 months of a year every weekday around 10PM.
H 20 20 1-6 * : Run the same job for 1st 6 months of a year once a month on the 20th day around 8PM
UPDATE:
Trying this now at 6.40 PM
H 10 * * *
H 15 * * *
Gives,
Would last have run at Thursday, June 15, 2017 3:45:32 PM; would next run at Friday, June 16, 2017 10:59:32 AM.
Which seems to suggest both schedules were accepted by Jenkins!
The Parameterized Scheduler plugin also adds the ability to have different parameters per schedule, so if you have something like a backup job that you want to run in multiple environments, you can have it scheduled three times in one night, once for each environment.
But otherwise, if you just need to have more than one schedule, adding one schedule per line should work just fine (with no extra plugins).
I have a Jenkins job that runs every day at 8:30 AM.
I want the job not to run on Fridays. Is there a way to achieve this ?
You can use the dow (day of week) to achieve it:
30 8 * * 0-4,6 your_command
# 0=Sunday 6=Saturday
My goal is to trigger a report every first weekday of the month at 7AM (7/1/15,8/3/15,9/1/15, etc.)
I am using the following cron expression: H 7 1-3/3 * 1-5
It runs on July 1, but it is not scheduled next to run on August 3, but on September 1. How can I get it to run on the first weekday of every month?
I am using the following help guide:
MINUTE Minutes within the hour (0–59)
HOUR The hour of the day (0–23)
DOM The day of the month (1–31)
MONTH The month (1–12)
DOW The day of the week (0–7) where 0 and 7 are Sunday.
To specify multiple values for one field, the following operators are available. In the order of precedence,
The * specifies all valid values
M-N specifies a range of values
M-N/X or */X steps by intervals of X through the specified range or whole valid range
A,B,...,Z enumerates multiple values
To allow periodically scheduled tasks to produce even load on the system, the symbol H (for “hash”) should be used wherever possible.
First weekday of the month rules:
If today is a Monday, then the job should be run if today is also the 1st, 2nd, or 3rd of the month
If today is a Tuesday, Wednesday, Thursday, or Friday, then the job should be run if today is also the 1st of the month
The following cron expressions should do the job:
H 7 1-3 * 1
H 7 1 * 2
H 7 1 * 3
H 7 1 * 4
H 7 1 * 5
# Would last have run at Wednesday, July 1, 2015 7:00:02 AM EEST; would next run at Monday, August 3, 2015 7:00:02 AM EEST.
Beware, because of this article, you can't just use:
H 7 1-3 * 1
H 7 1 * 2-5
The above doesn't work! Instead, the job is run on every weekday, twice on the 1st of the month, and maybe twice on the 2nd and 3rd of the month!
But I was not able to reproduce it.
This should work just fine:
H 7 1-3 * 1
H 7 1 * 2-5
The article to which the accepted answer is referred to is about crontab expressions. Jenkins cron expressions actually use AND for DOM and DOW (otherwise the solution from the accepted answer wouldn't work either)
Here is the answer to your question, seems it can work
