Schedule job to run periodically - jenkins

I am trying to run Jenkins job everyday at 10 AM and 10 PM . How do i do that?
Currently i use the below to run at 12 AM and 12 PM . Am not aware how to change it.
0 0-23/12 * * *

Its difficult to acheive it with just a single crontab entry, what you can do is to have a 2 crontab entry like below :-
for job which you want to run daily at 10 AM :-
0 10 * * *
And for 10 PM job 0 22 * * *.
Here first entry denotes the minute, second denotes the hour and then day,month and week.

Just click the "?" icon to the right of the "Schedule" field, and you'll see a detailed explanation of the syntax available there.
If you want it to run at 12am and 12pm, I would guess you would just do this:
0 0,12 * * *

Suppose you want to run a jenkins job at 4:30 AM , monday to saturday, then you can use below script under your jenkins build trigger:
30 04 * * 1-6
1-6 denotes monday to saturday
Coming back to your question, you can configure 2 entries under your build trigger to run Jenkins job everyday at 10 AM and 10 PM in jenkins as shown below:
00 10 * * 1-7
00 22 * * 1-7

Jenkins build periodically every 2 hours after 10 PM to next day 7AM

H H(22-7)/2 * * 1-5 ----- not working
Please let me know correct example
0 0,2,4,6,22 * * *
This will trigger the job at 10 PM, 12 AM, 2 AM, 4 AM and 6 AM everyday.
In case you need to distribute load, you can replace the first 0 with an H.

How do I schedule a build job in Jenkins from 8 PM to 6 AM?

I need to schedule a Jenkins job for every minute from 8 PM to 6 AM. Is there any way to do this in Jenkins? The hour options are from 0-23: for example it will work with * 6-20 * * * (from 6 am to 8 pm) but I want something like * 20-6 * * *.
You can apply more than one schedule for a Jenkins job.
0 0/1 20/1 ? * * *
0 0/1 0-6 ? * * *
The first expression will build the job every minute starting at minute 00, every hour starting at 20:00, of every day.
The second expression will build the job every minute starting at minute 00, every hour between 00:00 and 06:00, of every day.
In this way the job is scheduled to build every minute from 8 PM to 6 AM.

Jenkins Cron Syntax - How to Perform a Half of Hour

The requirement for my pipeline schedule is from 09:00 pm to 04:30 am I wrote the schedule like this triggers { cron('H H(21-4:30) * * *') } but it did not work, so how to correct this?
I think following cron will work for you.
H/30 21-23,0-4 * * *
At every 30th minute past every hour from 21 through 23 and every hour from 0 through 4.

How to set two different scheduler for single Jenkins job

I just want to run the job twice per week. Every Sunday 11 PM and every Friday 11 pm I just want to trigger the job automatically. I successfully implemented for one scheduler but not sure how to use two in single .
Sunday scheduler :
H 11 * * 0
Friday scheduler:
H 11 * * 6
For scheduling the job below pattern need to be followed:-
0 - Sun Sunday
1 - Mon Monday
2 - Tue Tuesday
3 - Wed Wednesday
4 - Thu Thursday
5 - Fri Friday
6 - Sat Saturday
7 - Sun Sunday
For your case you can follow the below:-
0 23 * * 0,5
You better understanding of "H" in Jobs Scheduler follow this:
Maybe something like this. Note there's a couple changes from your example, changed 11 to 23, 11 is 11am, 23 is 11pm and using 5 instead of 6 for Friday.
H 23 * * 0,5
But note with the "H" it isn't going to run at exactly 11pm, from the Jenkins docs:
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.
If you want it to run closer to 11pm, maybe something like this
H(1-5) 23 * * 0,5

Jenkins scheduled job

Is possible to scheduled a jenkins job to repeat a task every 45 min in a time interval?
Example (Repeat the job every 45 min as many times as possible since 10:00 am to 16:00 pm) - result would be 8 executions.
Thanks!!!
Yes. In the job configuration page, search for the section Build Triggers. In this section, enable Build periodically and put the following lines:
0,45 0-23/3 * * *
30 1-23/3 * * *
15 2-23/3 * * *
Reference: Is the following cron expression means every 45 minutes?
Explanation:
0,45 means to run at 0 mins and 45 mins for ex. 2 am and 2:45 am
0-23/3 in hour field means that a particular activity has to be performed every 3 hrs. In this case, it means 0, 3, 6, 9,... till 21 hrs (or 2100 hrs). Similarly for others.
So, first line i.e., 0,45 0-23/3 * * * takes care of 0000 hrs and 0045 hrs. Next time (+45 mins) will be 0130 hrs which will be taken care by 30 1-23/3 * * * and so on.
