How do I schedule jobs in Jenkins

Question

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

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

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
