What type of motion do I need to file to extend my set court date?

I need to change my set court date to extend it. I searched thoroughly online on all motion forms for my state. The only motion I found to ask for an extension is: (I)(1)(B): Motion for an extension of time. But I spoke with the court directly via cell phone to ask how, which Motion to file in order to extend my already set date for appearance. She told me there are two forms-motions, I would have to use. I'm confused because these two motion forms weren't listed anywhere while I was searching. The forms are: 1. Motion to Continue. 2. Order to Continue or Continuous? What do these motions mean, vs. the Motion for an extension of time? What's the difference? There is another motion form online I would like to know in legal terms what it means. IT IS: (I)(1)-Motions that that may be acted on without waiting a response.
