What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Unfortunately, JotForm doesn't have the ability to restrict date with respect to dynamic choices, but you can set fixed time to restrict date into your date field.
To understand it better, you can check the document about Limiting Dates.
If we come to your point, I'm going to raise this post as a feature request, so our developers will know about this issue.
If you need any other information, please feel free to contact us.
Sorry for the delay, this is now possible. You can enter the arrival date id as the start date in the date limits for the departure field:
