How do I schedule jobs in Jenkins?


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?

Enter image description here

The job should run at 4:20 AM, but it is not running.

The Best Answer is


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:

  1. MINUTES Minutes in one hour (0-59)
  2. HOURS Hours in one day (0-23)
  3. DAYMONTH Day in a month (1-31)
  4. MONTH Month in a year (1-12)
  5. 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.

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
