How to Set a 24-Hour HH:MM Time Field in Adobe Acrobat Forms
Question details
The user needs to configure a PDF form field to allow time entry or selection specifically in a 24-hour hour-and-minute format (HH:MM).
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Creating or editing an interactive PDF form where users are required to input a specific time of day.
- Observed behavior
- The goal is to strictly format the user input to display as a 24-hour time format rather than plain text or a 12-hour format.
Ensure you have your PDF form open in Edit mode and that you have already created the text field you wish to format as a time input.
Configure Field Properties for HH:MM Time Format
Use Adobe Acrobat's built-in field properties to set the specific format category to Time and choose the 24-hour layout.
Adobe Acrobat includes preset formatting options for text fields, which automatically validate and convert user input into standardized formats like dates and times. By selecting the HH:MM preset, the form will ensure data consistency without requiring custom JavaScript.
Right-click the specific text field you want to modify in your PDF document and select 'Properties' from the context menu.
In the Text Field Properties dialog box, click on the 'Format' tab located at the top of the window.
Click the 'Select format category' drop-down menu and choose 'Time' from the list of available categories.
In the 'Time Options' list that appears, scroll to find and select 'HH:MM'. Click 'Close' at the bottom of the dialog box to apply and save your changes.

Frequently Asked Questions
Can I set a 12-hour format instead of a 24-hour format?
Yes, in the Format tab under the Time category, you can select 'h:MM tt' for a standard 12-hour time format which includes AM/PM indicators.
Why isn't the format applying as I type?
The format typically applies only after the user finishes typing and clicks or tabs out of the field. Ensure you haven't set up custom keystroke validation scripts that might conflict with the standard time format.
How can I make the time field mandatory to fill out?
In the Text Field Properties dialog box, navigate to the General tab and check the 'Required' box at the bottom. This ensures the form cannot be submitted or finalized without a valid time entry in that specific field.
Does this HH:MM format work on mobile PDF viewers?
The format enforcement relies on the PDF reader's capabilities. While Adobe Acrobat Reader on mobile fully supports it, some third-party or built-in mobile PDF viewers might not enforce the formatting script accurately.
