if you get ranking with your current meta tag , then there is no need to change it. You need to change your meta tag when you loose your ranking.
Usually its not the time gap to change the meta tag. But you need to know how long it takes for the search engines to index and soak your meta tag. Most often it would take anywhere from 4 to 8 weeks.
If you have your meta descriptions the way you want them, don't change them unless you feel you can improve them. You can change your title anytime you want, if your research comes up with some better, keyword-rich phrasing.
