I need to schedule my Jenkins build at 2 AM everyday, except for Sunday. On Sunday, it should build at 10 AM.
For the first part, I have used H 2 * * *. Now I need to know what should I use along with this so that the jobs builds at 10 AM only on Sundays.
Any help would be greatly appreciated.
So what I understood, you would like to setup multiple cron entries.
First entry is for Monday to Saturday and second entry is only for Sunday.
Using the Using the job-dsl syntax, you can do it like below way:
triggers {
cron('example entry 1 \n example entry 2')}
Please refer this>>https://jenkinsci.github.io/job-dsl-plugin/#path/freeStyleJob-triggers-cron
As per the above link,use a single trigger string with entries separated by \n to configure multi line entry.
Cron support string parameter.
cron('example entry 1' + '\n example entry 2' + '\n example entry 3 *')
Thanks.
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
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 currently have a Jenkins job that is scheduled to run every 30 mins every day. It is configured as this: H/30 * * * *
I'd like to also tell the scheduler to run every 30 mins except from 2-3am. Is this possible? I can't seem to find exclusions in the schedule documentation.
I think I figured this one out after all.
H/30 0,1,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23 * * *
You need to explicitly set the hours by which you want the job to run, so in the csv list add all hours, except for 2 to keep tests from running between 2am and 2:59am
I added a new job in Jenkins, which I want to schedule periodically.
From Configure job, I am checking the "Build Periodically" checkbox and in the Schedule text field added the expression:
15 13 * * *
But it does not run at the scheduled time.
Is it the correct procedure to schedule a job?
The job should run at 4:20 AM, but it is not running.
By setting the schedule period to 15 13 * * * you tell Jenkins to schedule the build every day of every month of every year at the 15th minute of the 13th hour of the day.
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
If you want to schedule your build every 5 minutes, this will do the job : */5 * * * *
If you want to schedule your build every day at 8h00, this will do the job : 0 8 * * *
For the past few versions (2014), Jenkins have a new parameter, H (extract from the Jenkins code documentation):
To allow periodically scheduled tasks to produce even load on the system, the symbol H (for “hash”) should be used wherever possible.
For example, using 0 0 * * * for a dozen daily jobs will cause a large spike at midnight. In contrast, using H H * * * would still execute each job once a day, but not all at the same time, better using limited resources.
Note also that:
The H symbol can be thought of as a random value over a range, but it actually is a hash of the job name, not a random function, so that the value remains stable for any given project.
More example of using 'H'
The format is as follows:
MINUTE (0-59), HOUR (0-23), DAY (1-31), MONTH (1-12), DAY OF THE WEEK (0-6)
The letter H, representing the word Hash can be inserted instead of any of the values. It will calculate the parameter based on the hash code of you project name.
This is so that if you are building several projects on your build machine at the same time, let’s say midnight each day, they do not all start their build execution at the same time. Each project starts its execution at a different minute depending on its hash code.
You can also specify the value to be between numbers, i.e. H(0,30) will return the hash code of the project where the possible hashes are 0-30.
Examples:
Start build daily at 08:30 in the morning, Monday - Friday: 30 08 * * 1-5
Weekday daily build twice a day, at lunchtime 12:00 and midnight 00:00, Sunday to Thursday: 00 0,12 * * 0-4
Start build daily in the late afternoon between 4:00 p.m. - 4:59 p.m. or 16:00 -16:59 depending on the projects hash: H 16 * * 1-5
Start build at midnight: #midnight or start build at midnight, every Saturday: 59 23 * * 6
Every first of every month between 2:00 a.m. - 02:30 a.m.: H(0,30) 02 01 * *
Jenkins lets you set up multiple times, separated by line breaks.
If you need it to build daily at 7 am, along with every Sunday at 4 pm, the below works well.
H 7 * * *
H 16 * * 0
*/5 * * * * means every 5 minutes
5 * * * * means the 5th minute of every hour
The steps for scheduling jobs in Jenkins:
click on "Configure" of the job requirement
scroll down to "Build Triggers" - subtitle
Click on the checkBox of Build periodically
Add time schedule in the Schedule field, for example: #midnight
Note: under the schedule field, can see the last and the next date-time run.
Jenkins also supports predefined aliases to schedule build:
#hourly, #daily, #weekly, #monthly, #midnight
#hourly --> Build every hour at the beginning of the hour --> 0 * * * *
#daily, #midnight --> Build every day at midnight --> 0 0 * * *
#weekly --> Build every week at midnight on Sunday morning --> 0 0 * * 0
#monthly --> Build every month at midnight of the first day of the month --> 0 0 1 * *
Another example, How to run only on a specific day of the week:
# Every Sunday at 19:00
0 19 * * 0
The number at the end is the day of the week according to the following list:
0 = Sunday
1 = Monday
2 = Tuesday
3 = Wednesday
4 = Thursday
5 = Friday
6 = Saturday
If you are interested in how many days a week you can add a comma like this:
# Monday, Wednesday and Friday:
0 19 * * 1,3,5
Jenkins Job Scheduling Syntax
First, let’s look at the Jenkins job scheduling configuration. It looks a lot like Linux’s cron syntax, but you don’t have to be familiar with command line Linux to figure it out.
A scheduling entry consists of five whitespace-separated fields. You can schedule a job for more than one time by adding more than one entry.
Screenshot
Each field can contain an exact value or use a set of special expressions:
The familiar asterisk * indicates all valid values. So, a job that runs every day has a * in the third field.
A dash separates ranges of values. For example, a job that runs every hour from 9:00 a.m. to 5:00 p.m. would have 9-17 in the second field.
Intervals are specified with a slash /. A job that runs every 15 minutes has H/15 in the first field. Note that the H in the first field has a special meaning. If you wanted a job to run every 15 minutes, you could configure it as 0/15, which would make it run at the start of every hour. However, if you configure too many jobs this way, you can overload your Jenkins controller. Ultimately, the H tells Jenkins to pick a minute based on a hash of the job name.
Finally, you can specify multiple values with a comma. So, a job that runs Monday, Wednesday, and Friday would have 1,3,5 in the fifth field.
Jenkins provides a few examples in their help section for scheduling.
Every fifteen minutes (perhaps at :07, :22, :37, :52):
H/15 * * * *
Every ten minutes in the first half of every hour (three times,
perhaps at :04, :14, :24):
H(0-29)/10 * * * *
Once every two hours at 45 minutes past the hour starting at 9:45 AM
and finishing at 3:45 PM every weekday:
45 9-16/2 * * 1-5
Once in every two hour slot between 8 AM and 4 PM every weekday
(perhaps at 9:38 AM, 11:38 AM, 1:38 PM, 3:38 PM):
H H(8-15)/2 * * 1-5
Once a day on the 1st and 15th of every month except December:
H H 1,15 1-11 *
Jenkins also has a set of aliases that makes using common intervals easier.

To schedule a cron job every 5 minutes, you need to define the cron settings like this:
*/5 * * * *
Try this.
20 4 * * *
Check the below Screenshot
Referred URL - https://www.lenar.io/jenkins-schedule-build-periodically/
Try using 0 8 * * *. It should work
Jenkins uses Cron format on scheduling.
You can refer this link for more detailhttps://en.wikipedia.org/wiki/Cron.
One more thing, Jenkins provide us a very useful preview. Please take a look on the screenshot.
I hope this help. Thanks
