Can anyone suggest a way to set a Cron trigger to run at half past the hour every hour?
So far, I've got one working hourly as per "0 0/60 * * * ?".
Am I looking at "0 0/30 * * * ?" at all?
Mr Morgan.
I would use 30 * * * * to run a command half past every hour.
It is worth remembering that in crontab you define a pattern to match the current time against and not an exact time. Every minute crond will awaken and match the current time against your pattern and if there is a match, run your command.
I recommend using http://www.cronmaker.com/ for painless cron expressions.
Use this:
0 0/30 * * * ?
and not "30 * * * *" as this will trigger in every 30 seconds.
I know this was asked years ago but the correct cron syntax for half past trigger will be:
30 * 1/1 * ? *

I might be overlooking over already-asked-question, but I have not found it yet. Basically, did I do it right in order to execute job for every minute within 9 AM to 6 PM?
schedule.scheduleJob("*/1 9-18 * * *", function Job())
The cron expression should be 0 * 9-18 ? * * *
It reads 0 seconds, every minute, from 9 to 18 every day, every month, every year.
Use cron expression builder for convenience - something like this:

I am looking for cron syntax to execute:-
1- For every 30 minutes daily
2- From 7:00 AM to 1:00 AM(Midnight)
After reading blogs I could only manage to get */30 * * * * this.
This would be an option:
*/30 7-23,0-1 * * *
As long as you can only set consecutive hours from 0h to 23h and you need to run from 7am to 1am I think it fits your needs, despite using two hourly-based conditions in the same job.
I am having troubles with cron syntax,
I want to run cron job every 10 minutes,but not on 10th minute.
it has to run on 20,30,40,50,00 of the hour, not on 10.
How I do this?
10-59/10 * * * * doesn't work.
Add all times when the Job should be executed
0,20,30,40,50 * * * *
I need to run a cron job on the 3rd minute of every hour, every day.
Here's what I currently have:
3 * * * *
Is that how you correctly do it or would that run it every 3 minutes instead?
That is correct!
If you would like to run a job every third minute you could do like this:
*/3 * * * *
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 * * ?
