- Scenario
- Creating or editing a fillable PDF form that requires a standardized, auto-updating date field.
- Observed behavior
- The PDF form needs to securely and consistently display today's date automatically when opened by end-users on various systems (e.g., English or French).
Ensure you have a PDF editing tool with form creation and JavaScript capabilities, and verify the exact name of your intended date text field before applying the script.
Use Document-Level JavaScript to Auto-Populate the Date
Add a simple script to the PDF that triggers when the document opens, forcing the date field to display today's date in a specified format.
This method is ideal if you want a fully automated date that users cannot accidentally modify. By executing a document-level script on launch, the date calculates locally but outputs in a fixed format, bypassing the user's localized system settings.
Select the form field, open 'Text Field Properties', and enable 'Read Only' so users cannot manually change the date.
Open your PDF editor's JavaScript tool. Click 'Document JavaScripts' at the top of the menu and click 'Add' to create a new script.
Delete any placeholder text and enter the following script: var f = this.getField("Today"); f.value = util.printd("mm/dd/yyyy", new Date());
Replace 'Today' in the quotation marks with the exact case-sensitive name of your form field.
Click OK and Close. To test the form field, save the PDF, close it completely, and reopen the file to verify the date populates automatically.
Format a Date Field for Manual Selection
If you prefer users to select the date manually via a calendar drop-down, configure the field's formatting properties.

Frequently Asked Questions
Why is my PDF form date field not updating automatically?
The date field will only update automatically if you have added a document-level JavaScript that triggers upon opening. Without this script, a standard text or date field remains static or requires manual entry.
Is the JavaScript field name case-sensitive?
Yes, when using this.getField("YourFieldName") in your script, the text inside the quotation marks must match the exact capitalization and spelling of the form field's name.
Can I lock the date field so users cannot change it?
Absolutely. By opening the text field properties and checking the 'Read Only' box, you prevent end-users from modifying the automatically generated date.
Will the date format change if someone opens the PDF in another country?
If you use the JavaScript util.printd method, the format is hardcoded and will consistently display the same way regardless of the viewer's local system or regional settings.
