jira - run cron every 2 days

[Gavin]

Hi I'm trying to run a cron every 2 days at 9am.

I thought this would work

0 0 9/2 * * ?

But I'm getting those triggered at 1pm and 3pM.  I think ever 2 hrs after that.  

what am I doing wrong.

thanks

Should it be….? Haven’t tested…

0 9 */2 * *

minute hour dom month dow 

note the time is GMT so if you want local time add offset.

[Gavin]

0 9 */2 * * says Unexpected end of expression

[Gavin]

0 9 */2 * * ? this worked.. question does this mean the same thing?

[Jack Brickey]

Does it mean the same thing as what? As what you were looking for? I believe so but only you can say for sure via your testing. 

[Gavin]

thanks.

is there any way to check the cron instead of edit and wait?

[Jack Brickey]

You could test out the format on minutes…

*/5 * * * *

[Gavin]

hmm ok I have this as my cron job

0 9 */2 * * ?  - verified it from https://crontab.guru/#0_9_*/2_*_*  as supposes to be running every 2 days. However, https://support.atlassian.com/jira-software-cloud/docs/construct-cron-expressions-for-a-filter-subscription/ seems different. the 9 is a minute time and the /2 hrs.

But looks like it's running every 2 hrs.

audit log shows it running at 

6:09

8:09

10:09

so apparently atlassian is using their own version of cron.

so 0 9 */2 * * ? should be 0 0 9 */2 ? *  is my thinking right?

Hi, I just ran into this post. I think what you are looking for is 0 9 * * 1-7/2 which runs on every second day of the week :)
