How do I get a form to calculate hours worked?

[Tori5ECE]

I have a pdf timecard that I needed to adapt to an hourly employee. 

I have read lots of things on here and alot of them say to use JavaScript...I have no clue how or what that is. 

I am attaching the for I have, and am hoping someone can wlak me thru step by step in how to get the IN and OUT boxes to TOTAL the hours worked.  Then to get the TOTAL at the bottom to show the total hours. 

ex. IN: 8:00 am  OUT 2:00 pm  TOTAL: 6 hours

Any help is appreciated!

Hi there

Hope you are doing well and thank you  for reaching out.

The workflow you are trying to achieve is posible using the JavaScript. For more information about using the JavaScript please check the help page - https://acrobatusers.com/tutorials/javascript_console/

Working with date and time in Acrobat is not a simple task. You can start by reading these tutorials:

If you're interested, I've developed a (paid-for) tool that will allow you to set up such calculations very easily, without having to write any code. You can find it here: https://www.try67.com/tool/acrobat-calculate-time-differences-in-a-worksheet
