How to Write Cron expression to Schedule alert on @ 11am, Every month on 2nd Wednesday,Thursday,Friday?

Hi Splunkers,

We need to schedule alert for Every month on 2nd Wednesday,Thursday and Friday on @11 am. I have tried with below Cron Expression but i didn't get exact results.

Cron Expression: 0 11 8-14 * 3-4

Please provide proper cron expression.

Hello @ajayabburi508

if you specify both days of month and days of week, they are combined with an "OR"

Commands are executed by cron(8) when the 'minute', 'hour', and 'month of the year' fields match the current time, and at least one of the two 'day' fields ('day of month', or 'day of week') match the current time.

0 11 * * 3-5 “At 11:00 on every day-of-week from Wednesday through Friday.” https://crontab.guru/#0_11_*_*_3-5

0 11 8-14 * 3-5 “At 11:00 on every day-of-month from 8 through 14 and on every day-of-week from Wednesday through Friday.” https://crontab.guru/#0_11_8-14_*_3-5

So you can use the first version 0 11 * * 3-5 and discard 12-14 results/month or 0 11 8-14 * * and discard 4 results/month

This is not working can you provide exact expression which is working in crontab related to my question.

@ajayabburi508 it seems it is not possible with one single expression, both provided expressions are partial workarounds but not the solution that you asked
