How to add validation for the date field in issue create screen

[Sandesh TM]

We need to add validations for the custom date field in the issue create screen. How can we achieve that?

Usually, through a workflow validator. If you have a validator (might need a plugin I'm afraid) there then it validates on "Create" button. Meaning if the date is not valid, then the user gets an error message (usually customizable to indicate the field w/ message), forcing them to change the value before trying again.

Out of box I don't think you can validate custom fields, but perhaps they added something in data center that I don't recall. Look around the validator options though if it contains something you could use.
