Do I need to use javascript to get a text field in a PDF form to aut fill with current/today's date?

I have a form for booking appointments and would like the date field to automatically fill with

today's date and to print. I have set the text field's format to "Date" and when I place the cursor into the

date field, today's date shows. It disappears as soon as I tab to the next field.

Does this action require a javascript script to fill and print today's date? If so, where do I find that?

Or is there another way to format the text field (besides typing today's date) to get the current date?

Thanks.
