Fix Adobe Acrobat PDF Form Dates Displaying in the Wrong Language
Question details
The user needs to ensure that dates selected from a PDF form date picker are inserted in the correct local language instead of defaulting to English.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Filling out interactive PDF forms with localized date formats (e.g., Swedish or Slovak).
- Observed behavior
- The date picker UI displays the correct localized language, but the text inserted into the form field remains in English.
Ensure you know the exact version of Adobe Acrobat or Reader you are using, as language and localization settings can vary significantly between different builds.
Match the Acrobat Language Version to the Form Language
Installing the specific language version of Acrobat (e.g., Swedish or Slovak) aligns the internal date formatting engine with the document's language.
Acrobat sometimes handles the date picker UI and the actual inserted text value using separate localization processes. Using a fully localized version of the software can resolve this mismatch.
Open Adobe Acrobat, navigate to Edit > Preferences, and select 'Language' to see your current application language settings.
Visit the official Adobe download page and explicitly select the specific language version (e.g., Slovak or Swedish) of Acrobat Reader DC that matches your PDF form.
Install the new language-specific version, open your PDF form, and use the date picker to verify if the populated text now inserts in the correct language.

Report the Issue to Adobe Support
If the issue persists even when using the correct localized version of Acrobat, it is likely a software bug that needs to be reported for a patch.

Frequently Asked Questions
Why does the PDF date picker show one language but type another?
This usually happens when the document's language settings differ from the application's underlying localization, or due to a known bug in certain versions of Adobe Acrobat where the form field inherits the system's default language (English) instead of the picker's language.
Can I change the date format in a PDF form?
Yes, if you are the form creator, you can right-click the date field in Acrobat's Prepare Form mode, select Properties, go to the Format tab, and choose or customize the date format (e.g., 'dd mmmm yyyy').
Does changing my operating system language fix the PDF date issue?
Sometimes changing your operating system regional and language settings to match the desired language can force the PDF reader to populate dates correctly, but it is more reliable to use a localized version of the PDF reader itself.
How do I check the document language of my PDF?
In Adobe Acrobat or Reader, go to File > Properties, then click on the Advanced tab. Look under the Reading Options section to see the Language currently selected for the document.
