- Scenario
- Creating or formatting an interactive PDF form that requires a date field to automatically pre-fill with the date of the following day.
- Observed behavior
- A custom JavaScript snippet is needed to create a date object, add one day to it, and format it into the specified PDF form field.
Ensure you have a PDF editor that supports Document JavaScripts and that the text field you intend to populate with the date has already been created and named.
Use JavaScript to Calculate and Format Tomorrow's Date
You can dynamically set a form field to tomorrow's date by manipulating the JavaScript Date object to add one day before printing it to the field.
By default, standard date fields often default to today. To display tomorrow, we must intercept the date calculation using a short JavaScript snippet.
The script targets a specific field by its name, grabs the current date, increments the day by 1, and applies a specific formatting style.
Open your PDF in form editing mode and note the exact name of your date field. For this example, we assume the field is named "Today".
Navigate to your PDF editor's JavaScript or Action settings. You can add this script as a Page Open action or a Document Level script depending on when you want the field to populate.
Enter the following code: var f = this.getField("Today"); var d = new Date(); d.setDate(d.getDate() + 1); f.value = util.printd("dd/mm/yyyy", d);
Apply the script, save your PDF document, and preview the form. The field should now accurately display tomorrow's date in the dd/mm/yyyy format.

Frequently Asked Questions
Can I change the date format to US style (Month/Day/Year)?
Yes, you can modify the formatting segment of the JavaScript code. Change `util.printd("dd/mm/yyyy", d)` to `util.printd("mm/dd/yyyy", d)` to output the date in the US format.
Why is the PDF form field remaining blank?
A blank field usually means either JavaScript is disabled in your PDF reader's security settings, or the field name in the script (e.g., "Today") does not perfectly match the actual name of the form field in your PDF.
How do I set the date to one week from today?
To set the date 7 days into the future, adjust the addition in the Date object line. Change `d.setDate(d.getDate() + 1);` to `d.setDate(d.getDate() + 7);`.
