Not able to set last day of month, Any Idea ?

[chiraggupta01]

I need to set the last day of the month, which can be either the 30th or 31st, depending on the month. As we know, each month has a different number of days, so if I select the 31st while scheduling my CRON job, it will skip months that do not have 31 days. This is where things go wrong, and it will not work properly.

I would like to understand if there is a way to set the last day of the month in the date dropdown or in any other way.
