CRON

[Kieron Brent]

I would like to write a CRON expression to only trigger on a weekday between the hours of 0800 and 1800 and once every 45 minutes.  I thought I had solved this using this CRON expression but it doesn't seem to work.  Any help welcome, thanks.

0 45 8,18 ? * 1-5

Hi @Kieron Brent 

Welcome to the Atlassian Community!

You can try below cron expression for your use case, since you want to use an hour range, you should use - instead of , for hour field, so that it triggers only between that hour range(i.e between 8AM -6PM)

0 0/45 8-18 ? * MON-FRI *

Hi @Kieron Brent , welcome to the community!

(Edited to correct the expression per @Kishan Sharma's answer [he's correct] for future reference by others, thx!)

Have you tried  0 0/45 8-18 ? * MON-FRI *  ? Also, there are a couple of good sites I use for CRON expressions, crontab.guru and a Community page Constructing cron expressions for a filter expression. Hope these help!

I will let you know a little later if this has worked - Thanks
