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 ? *

Thanks,

We work on a product whose software development team applies patch on every 1st Friday of the month. We have written some tests that we run on the Sunday after the patch is applied. So to automate the same on Jenkins, we would need a cron that runs on 1st Sunday after the 1st Friday of the month has passed.
Right now we just update our Jenkins each month considering dates, but can we automate this?
Thanks
Naively, one would suppose that 0 3 1-7 * fri would be "3am on the Friday that falls inside the first week of each month", and then we could use the similar logic to construct 0 3 3-9 * sun, for the Sunday that follows two days after such a Friday.
Unfortunately, this does not work, because day of week and day of month are taken as a disjunction by the cron specification; which means, the above would trigger not on the Sunday following the first Friday in a month, but on every Sunday, and also every day from 3rd to 9th.
Due to this twist in cron spec, what you ask is not possible by cron alone. The easiest way to untangle this is to separate the two requirements, ask the cron to track one of them, and manually test the other: either use 0 3 3-9 * * and then manually test in your script whether the day is Sunday and exit without performing your task if it is not, or use 0 3 * * sun and manually make sure the date is between 3rd and 9th.
I have created my job and want to trigger build daily at 11am and in any other time I should not be able to trigger it.
You can Go to “Build Triggers” section in jenkins and under that Check “Poll SCM”, here you can create cron jon for your pipeline trigger.
For you query you can give somethind like below in the Poll SCM schedule box:
0 11 * * *
Jenkins used a cron expression, and the different fields are:
MINUTES Minutes in one hour (0-59)
HOURS Hours in one day (0-23)
DAYMONTH Day in a month (1-31)
MONTH Month in a year (1-12)
DAYWEEK Day of the week (0-7) where 0 and 7 are sunday

To add on the given answer , you can also add a simple bash script to check the time and exit or do the same in the jenkins pipeline
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 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
I've set up a Jenkins job and set the poll interval at 1 minute (I used this syntax 0 * * * *).
Looking in the Polling log I can see its reported that a poll call was made as soon as I saved the changes to the job.
But not over 10 minutes later it hasn't made any other polls.
Any suggestions how I can proceed determining the problem?
You're looking for "* * * * *".
Jenkins gives a warning since every minute can be a bit excessive, but your version control server shouldn't have any problems handling the load.
Your cron syntax is set to poll once per hour, at zero minutes past the hour. From the Jenkins help text:
This field follows the syntax of cron (with minor differences). Specifically, each line consists of 5 fields separated by TAB or whitespace:
MINUTE HOUR DOM MONTH DOW
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.
