It depends on how much training you will do each week.
I always recomend planning to finish your training in Spring so that you have the summer with your new licence to get some easier VFR flying in while the days are long. Getting your licence in October will mean you run the risk of getting rusty over the winter when weather and short daylight hours will restrict the amount of flying you can do.
So if you start now doing 2 hrs per week you'll be doing the dual work while the weather is bad, you may get some delays due to weather as you come onto the solo stuff but you should be finished by Easter in time to try out your new licence over the summer.
