How to run cron job on 29th of every month? [closed]

Question

Is it possible to write a single cron expression which runs on the 29^th day of every month OR the last day if the month has only 28 days (e.g. February)?

Answer 1

Single cron syntax is not possible. You can do last day of the month

0 0 12 L 1/1 ? *. 

It will trigger last day of every month.

0 0 12 29 1/1 ? *.

If you trigger like this you will miss non leap year February.
