When should I apply for an apartment?

I am graduating from college on December 14th and starting my Master's degree in January. I found an apartment complex that I can actually afford, for restricted income, but I'm not sure when to apply. I've never rented an apartment before, so bare with me. Should I be applying now or should I wait... show more I am graduating from college on December 14th and starting my Master's degree in January. I found an apartment complex that I can actually afford, for restricted income, but I'm not sure when to apply. I've never rented an apartment before, so bare with me. Should I be applying now or should I wait until December? I'd like to move in asap after December 14th, maybe even on December 14th. Does the application process normally take a long time?
For reference, I live in Savannah, GA.
