Can i go into a civil court on the date of court and get a extension?

Look up the court rules for magistrate court in your state. They should explain if you can do that and how. Sometimes a magistrate will allow an extension is you explain you are in the process of retaining an attorney. The clerk of the court may be able to explain how an extension is granted, but they can't answer legal questions.

to your house? call a builder. Your penis ? a surgeon.
No, a request for an extension has to be on file in the records of the clerk. But ask an attorney and do not seek ACTUAL legal advise on the inet. You may get lucky, but is a heck of a dice throw to ask for an answer that could be a life altering outcome.
most likely not the judge will not be happy since that was on his calender for that day and if he gave extension , then he can not schedule anything else that day wasting his/her time
