Since now is still Chinese/lunar New Year, I guess the last question sentence of your responsive sentence was “你过节要过到什么时候?” (Until when do you want to celebrate Chinese/lunar New Year?) (All I know is the main verb of the question is 过, so there may be other possibilities.)
So your friend answered, “Until anytime as long as you (or I/he/she, we cannot get specific subject from your sentence.) want.”
Just a guess, hope it can help you :)
