Is there a widget that I can use as scheduler?

I also need a scheduler for customers to complete as they will need to book sessions.  There are 16 different booths that are offering sessions every half and hour, for two days.  Is there a type of calender plug in for this using a form creation?  

We have several widgets to add more functionality to your JotForms. Since you want to enable the users to book the sessions, you may consider using the following widgets.
