can i add a link to a calendar tool to have someone schedule a time with me?

I'm not sure if I understand your question correctly, Do you want to display a date field with a calendar on your form so that your user can select the date on the form? If so, you may use the DateTime field from the quick tools section.

You may also consider taking a look at the following widgets that can help you with your requirement.

Yes, I looked at the appointment widget, is there a way that it connects to my calendar? I didn’t see that?
Otherwise, can I put a link on the form to my existing calendar scheduling tool?

To assist you better could you please indicate what calendar tool you wish to link jotform with. You may want to review our blog:

Unfortunately, integration with TimeTrade is not available at the moment. If you have a direct link to your existing calendar tool, you may insert the link using the Text field.
