How can I create a date picker for a PDF?

Hi.

the best and the cheapest is here: http://abracadabrapdf.net/utilities-in-english/acrobat-utilities/magicdate-picker/

FormRoouter offer a free tool for adding fields and some validation options. One of them is a date field with a date picker. Also www.pdfscriting.com by subscription offers a date picker tool. Max Wyss has one that uses the dialog object but you need to purchase it from him.

You can use 3 drop-down lists for day, month, and year.

Acrobat DC now has or soon will have a new form field to crreate a date field including a date picker.

If not then you need to add the needed code to the form. This code dynamically populates the correct number of days for the month and year being displayed. This might not be as simple as one might think. The code also puts the dates in the correct day of the week column.
