I am not sure how tn works but this happend to me as well. They can move the court date and they did with my case once. They tried to a second time and the court denied it. I think it just depends on the case and situation. You can call the judges assistant if you have questions. As far as the wrong days, are you sure they are wrong? You need to research and make sure you are figuring days out correctly. What is a full day, what is a half day and what is a quarter day. In arizona it is a 24 hour period that count for a full day and then it is broken down from there. When you get to court you will be able to state why your dates are right and hers are wrong. Have your child support worksheet done to reflect your time that you have researched and all of the documentation to support it. I am not sure if you have a lawyer, but either way it is good to have all the information and know your stuff before you go to court. Let me know if you have any more questions. I have been doing this by myself without legal council for the last 3 years and have done ok.
