How to Add a Date Picker Calendar to an Acrobat Dynamic Stamp
Question details
The user wants to add a calendar popup to an Acrobat dynamic stamp to select a specific date before placing it, rather than automatically inserting the current date.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Creating a custom dynamic stamp in Adobe Acrobat that requires user input for the date via a visual calendar picker.
- Observed behavior
- Acrobat automatically inserts the current date using standard JavaScript, lacking a built-in graphical calendar picker for dynamic stamps.
Ensure you have Adobe Acrobat Pro or Standard installed, as the free Adobe Reader cannot create custom dynamic stamps. Basic knowledge of Acrobat JavaScript is required to implement dialog-based scripts.
Embed a Dialog-Based JavaScript Calendar in the Stamp
Since Acrobat lacks a native modern calendar control for stamps, you must code a custom JavaScript dialog to prompt the user for a date.
Adobe Acrobat does not include a modern drop-down calendar element for its JavaScript engine. To achieve a date picker popup, you must construct a custom dialog using the app.execDialog method and embed it within your stamp's calculation script.
Open Adobe Acrobat, navigate to Tools > Stamp > Custom Stamps, and choose to create or edit your dynamic stamp PDF file.
Using the Prepare Form tool, double-click the text field inside your stamp that will display the date to open its Properties dialog.
Go to the 'Calculate' tab, select 'Custom calculation script', and click 'Edit' to open the JavaScript editor.
Insert a custom Acrobat dialog script (app.execDialog) designed for date selection. Ensure the script captures the user's input and assigns the formatted result to event.value.
Save the stamp file. When you place the stamp on a document, the custom JavaScript dialog will appear, allowing you to manually pick the date before it renders.
Manually Edit the Date After Placing the Stamp
A simpler, code-free alternative is to place a standard stamp and manually add a text box for the specific date.

Frequently Asked Questions
Can I use HTML5 date input types in Acrobat dynamic stamps?
No, Adobe Acrobat's JavaScript engine for dynamic stamps does not support HTML5 or modern web-based UI controls like `<input type="date">`. You must use Acrobat's specific `app.execDialog` object to create popups.
Why does my dynamic stamp always show the current date instead of asking for input?
By default, dynamic stamps use `util.printd` with `new Date()` to automatically grab the system time. To ask for user input, you must replace this automated script with a prompt (`app.response`) or a custom dialog script before setting the field value.
Do dynamic JavaScript stamps work when viewed in standard PDF readers?
Dynamic stamps function properly and execute their scripts when being placed using Adobe Acrobat. However, once the stamp is placed and saved, it becomes standard PDF content. The visual result can then be viewed perfectly in any standard PDF reader like WPS PDF.
