JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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.
I see that you want your form to be disabled at a scheduled time. To achieve your requirement, please follow the "Disable on Date" section from this guide: How to limit submissions in a form. If you need further assistance with setting it up, please let us know.
