CRON expression for last business day minus 2

[LRobinson]

Hi :) 

I'm trying to create to a CRON expression to run on the following:

every 3rd from last business day (LBD -2) at 8:30am every month

I thought i cracked it with:

0 30 8 LW-2 * ?

but it doesn't accept the '-2'

Is there another way I can do this or a simpler way?

Many thanks :)

Hello @LRobinson 

Welcome to the Atlassian community.

Where in Jira are you trying to use that CRON expression?

I don't see anything in the CRON documentation that indicates you can use "-2" in combination with LW for Day Of Month.

I don't believe it is actually possible to do what you want based on this CRON expression generator when the last working day of the month is a moving target for both date (28th, 29th, 30th, etc.) and day of week.

Hi Trudy,

Thank you for your response. I'm using this when trying to set a schedule for an automation. 

That is unfortunate. I'll have to figure something else.
