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.
I have submitted a feature request ticket to our higher team support on the feature to allow setting the Reservation Date Widget starting day of the week to be on Sundays.
I cannot provide you any time frame on the availability of this feature, but we will notify you here for any news/updates on the status when available.
Since your next question was about a different issue, I have created a separate post for it here http://www.jotform.com/answers/674872
We will attend to it shortly.
