Question details
The user needs to automatically fill daily date fields in a PDF timesheet based on a specified period start and end date.
- Product
- Adobe Acrobat PDF
- Device & OS
- not provided
- Scenario
- Creating a dynamic PDF timesheet where entering a start date automatically calculates and populates the dates for subsequent days.
- Observed behavior
- Sequential dates are calculated and populated automatically using JavaScript instead of requiring manual entry for each day.
Ensure that your PDF editor supports JavaScript for forms, and that you have named your date fields logically (e.g., Date1, Date2) to make the scripting process easier to manage.
Use Custom JavaScript to Auto-Populate Sequential Dates
Apply validation and calculation scripts to automatically calculate and fill intermediate dates based on an initial start date.
By utilizing Acrobat JavaScript, you can parse the initial date, perform date arithmetic to increment the days, and format the output for the remaining fields in your timesheet. This eliminates manual data entry and reduces errors.
Add a text field for the Start Date in your PDF form, right-click it, and open its Properties menu.
Under the Validate tab, choose 'Run custom validation script' to ensure the entered date meets your criteria, such as falling on a specific day of the week like Saturday.
Add the sequential date text fields where the calculated dates will appear, ensuring they have distinct, sequential names.
Use an on-blur or calculate script on the start date field to parse the date with util.scand, increment it using setDate, and output the formatted date to the subsequent fields using util.printd.

Frequently Asked Questions
Why aren't my sequential dates updating automatically?
This usually happens if JavaScript is disabled in your PDF viewer or if there is a syntax error in your calculation script. Check your software preferences to enable JavaScript, and review your script console for errors.
Can I format the dates differently, like DD/MM/YYYY?
Yes, you can change the date format by modifying the format string inside the util.printd function within your JavaScript code. Simply replace the format string with 'dd/mm/yyyy'.
Do these JavaScript calculations work on mobile PDF viewers?
Most mobile PDF viewers have limited or no support for custom JavaScript calculations. It is highly recommended to fill these dynamic forms using a desktop PDF application.
