How to add 2.5 hours ahead in the Time field?

I would like to have the submitter enter a start time and the end time auto fill with a calculated time.

For example,

If they enter 7 p.m. start, I would like the end time to automatically read 2.5 hours after the start time.

Start 7:00 PM End 9:30 PM

Thank you,

Hi Sandy Lynch,

Thanks for reaching out to Jotform Support. I've checked out the example you shared about your requirements for the time. You want to have 2 hours and 30 minutes added to the start time. Allow me some time to check on this and I will get back to you with an update.

Thanks for your patience and understanding; we appreciate it.

Thank you!

Hello,

I added time with a range.

I added a calculation field.

Unsure how to make it autofill the end range 2.5 hrs later.

For Start Nap Time I want to be able to enter a start time and the end time autofills in with a time that is 2.5 hrs after the start time.

Hi Sandy Lynch,

Thanks for patiently waiting. I've got an update on your request. The form URL you shared with us seems to be from the Enterprise account. Unfortunately, it is not possible to achieve the results using the time field. As a workaround, you can use the Date Picker Field with the time option enabled in it. Then you can use the Form Calculator widget to add the hours to the time field. Let me show you how to do it:

1. In Form Builder, click on the Add Form Element menu on the left side of the page. 
2. Scroll down and add the two Date Picker fields. Enable the time field option under the time tab.
3. Select the current option for the Date and Time fields in both elements.
4. Add Update/Calculate Field conditional logic to add the 2.30 hours ahead.

Here is my result:

Here is my demo form; you can check it out and clone it.

Let us know how it goes.

Looks to work! I have it being reviewing by the requestor to see if it fits their need. Thank you,
