Add a Date Field in Acrobat Form Editing Mode
Use the Prepare Form tool to insert a native Date Field, which automatically generates a pop-up calendar for users in supported Acrobat versions.
In modern versions of Adobe Acrobat Pro, creating a pop-up calendar is natively supported through the Date Field tool. You do not need to write custom JavaScript to achieve this functionality.
Launch Adobe Acrobat Pro, open your PDF document, navigate to the 'Tools' menu at the top, and select 'Prepare Form'.
In the Prepare Form toolbar, locate and click the 'Add a Date Field' icon (it looks like a small calendar).
Click on the specific area of the PDF page where you want the calendar control to appear. You can drag the corners to resize the field.
Double-click the newly created field to open its Properties dialog. Navigate to the 'Format' tab, select 'Date' from the Format Category dropdown, and pick your preferred date display format.
Click 'Preview' in the top right corner of the Acrobat window, then click the date field to verify that the pop-up calendar appears correctly.

Edit and Fill PDF Forms Easily with WPS Office
WPS Office provides a highly capable built-in PDF reader and editor that flawlessly handles interactive PDF forms. Whether you need to fill out date fields, check boxes, or manage text inputs, WPS PDF makes the process seamless.
- 1. Open Your PDF: Launch WPS Office and open your interactive PDF document using the WPS PDF tool.
- 2. Interact with the Form: Click directly on the designated date field within the document.
- 3. Select the Date: Choose your desired date from the pop-up calendar or manually type the date into the field.
- 4. Save the Completed Form: Click the 'Save' button in the top left corner or press Ctrl+S to save your form data securely.

Frequently Asked Questions
Why isn't the pop-up calendar appearing when I click the date field?
This usually happens if the PDF viewer you are using to open the file does not support interactive form features. Ensure you or your recipients are opening the document in a supported application like Adobe Acrobat Reader or WPS PDF.
Can I customize the date format of the pop-up calendar?
Yes. In Adobe Acrobat's Prepare Form mode, double-click the date field to access its Properties. Under the Format tab, you can choose from various preset date formats (e.g., mm/dd/yyyy, dd-mmm-yy) or create a custom one.
Do I need to use JavaScript to create a calendar in Acrobat?
Not anymore. While older versions of Acrobat (like Acrobat XI) required custom JavaScript to generate a calendar control, modern versions of Acrobat Pro include a native Date Field type that handles the pop-up calendar automatically.
