Adding placeholder text to formatted text field

Hello,

I have a text field formatted as a "date" or "mmmm d, yyyy" (or for example, "February 21, 2023").

However, I cannot use my normal way of applying placeholder text or that is, the Default Value, as I recieve the error "The defualt value does not match the format (Date) specified". 

Is there a simple way to add placeholder texts to a formatted field?

Apologies as I am quite new at this - many thanks for any help.
