hey, This might not be an exact solution to your problem, because you have not given much information on like, what is the range of a season.. when does that starts.. Is it quarterly and so on.. But i think the above code must help you a lot.. and you can re-arrange little bit of code to customize it as per your requirement.. anyway, i am just a comment away.
