I'm trying to write a Quartz task that runs on a cron schedule of every 10 minutes between 8am and 4:30pm.
If It was just between 8am and 4pm I would use
s m h dom M dow
0 */10 8-16 ? * MON-FRI
But I need it to run until 4:30 not just 4...
How can I do this?
I think it is impossible to express such requirement in one cron schedule . I would create two cron schedules instead :
0 */10 8-15 ? * MON-FRI (Run from 8:00am to 3:50pm every 10 minutes)
0 0,10,20,30 16 ? * MON-FRI (Run at 4:00pm , 4:10pm , 4:20pm , 4:30pm)
In this particular case you are probably better off using a DailyTimeIntervalTrigger rather than a CronTrigger. Here is a screenshot from QuartzDesk (our Quartz management and monitoring GUI) that shows you an example of a DailyTimeIntervalTrigger with attributes that meet your scheduling requirements:

I need to schedule a job in databricks that should run at 6am, 6.15, 6.30, 6.45, 7, 7.15, 7.30, 7.45 and 8am every day.
I am using below expression however it is not running at 8am. Is there anyway we can achieve this?
0 0,15,30,45 06,07 ? * *
This is expected behaviour from cron expression. As per your requirement, you need to write separate cron expression for the 08:00 as follows:
Note that some scheduling requirements are too complicated to express
with a single trigger - such as “every 5 minutes between 9:00 am and
10:00 am, and every 20 minutes between 1:00 pm and 10:00 pm”. The
solution in this scenario is to simply create two triggers, and
register both of them to run the same job.
This will run from 6.00 until 7.45, every 15 minutes:
* 0/15 06-07 * * *
If you want it to run until 08:00 then you have to create two triggers and register both if them to run the same job.
* 0/15 06-07 * * *
* 0 08 * * *
Reference: Databricks uses Quartz Cron triggers. Databricks – Cron Triggers
Hope this helps.
Run twice a day at 10:00 and 18:00
**0 0 10,18/12 * * ?**

I have a task which needs to be scheduled for every 15 min from Monday to Friday during Biz hours (UTC time based).
For the same task, I want to reduce the frequency of execution during weekend to 4 hrs.
For this scenario, cron would be:
*/15 00-01,12-23 * * 01-05
* */4 * * 06-07
Is there anyway to have a single cron instead of two separate cron job? Or can I, in any way, append the two cron jobs into a single one?
I have a case in which I'm migrating some tasks from Windows to a platform and we are using cron expressions to replace the Windows Scheduler.
Today we have something in Windows like At 10:20 AM every weekday, every 10 minutes for 9 hours. I'm trying to replace it with chron but I couldn't achieve it so far.
The closest I got is 0 20/10 10-19 * * MON-FRI. The thing is on this cron, it won't execute at 11:00, 12:00 and so on. We have a specific case in which we don't want it to execute at 10:00 AM.
The only option I found is to execute at 10:00AM and put some condition to validate it. Is it possible to achieve this result with only chron?
Thanks!
You can do it with cron, but you'll need to break it up into two schedules.
20/10 10 * * MON-FRI
and
*/10 11-19 * * MON-FRI
Btw, if this is cron on unix, there is no field for seconds.
I want a cron job to run between 7 AM and 10 PM, every day, at 5 minute intervals. Normally this would be okay if it was 5 minute intervals, because you could just use "/5", but is there a way to specify it as 5 minute intervals but skip the times between 10PM and 7AM?
The minutes are specified separately from the hours in crontab. Specify minutes using the periodic notation, and the hours as a range.
*/5 7-21 * * * /path/to/script
Below would help for Quartz scheduler
0 00/5 7-21 * * ?
I want a cron job (or a combination of 2 jobs) which fires at 00:00, 01:30, 03:00 and so on for all day. What can be the most succinct way to write the expression?
you need to split it into 2 jobs since it is an odd frequency
0 0-21/3 * * * command
30 1-22/3 * * * command
Use following cron expression to configure your cron trigger
0 0/30 0,23 * * ?
