I have searched a lot for a solution on the EventBridge for Amazon so I can use a cron which trigger a lambda function on the last day of the month in working days MON-FRI.
I cannot accomplish the working days part but here it is the last day cron.
30 13 L * ? *
This code will be triggered on the last day of the month. The ? is for every day but in fact I want 0-4 or MON-FRI.
If I enter it in the amazon cron tab it make an error for invalid cron expression.
You can use this cron expression : 30 13 LW * ? *
Here the L
wildcard in the Day-of-month fields specifies the last day of the month. And the W
wildcard in the Day-of-month field specifies a weekday. So in the Day-of-month field, LW
specifies the last weekday closest to the month.
