Everybody is different, and after a while you'll feel when ur body is tired or healed.
ppl will tell you to train like this or that, with so many rest days. But if your not pushing yourself hard you can train everyday. If you rip urself to bits you can only train once a week.
If you write down everything you do and compare it all you will get a better idea of how long it takes ur body to recover.
Sometimes you might train a muscle hard and its fine in 2days, but if ur not sleeping or eating right then it could take 4-5days to recover.
Sorry I cant be more specific, but it's best to work it out yourself than have some1 tell you, cos it may not suit you or ur lifestyle.
Some ppl may not agree but i got great results this way...
Instead of doing any particular body part, I have pushing days, and pulling days and core days.
Pushing days- chest, front+mid Delts, tri's, quads,Glutes, etc...
pulling days - Traps, lats, Bi's, calfs, rear delts,etc...
Core - lower back, abs, obliques int+ext, groin.
then on the 4th day you go back to pushing as youve had 2days rest.
