Your best bet would be to contact the magazine in question and ask, since it varies so much from mag to mag.
For example, I know one craft mag that needs to get your stuff in July if it's to get into their Christmas issue, and another that needs it in May since they're a trade mag.
I think in general you'd be looking at three to five months lead time, but if you ask you can also find out how they want things submitted, etc.
