I went through 4 years ago, so your results may vary, but...
Indoc:6 class days (1 week + 1 day)
Systems: 13 class days.
So basically you start on, say, Monday the 1st. You finish Systems on Thursday the 25th.
Then a break before FTD/Sims. This can be 12 hours. It can be 12 days. In my case it was 6 weeks.
FTD/Sims will take about 4 weeks depending on sim availability. I got mine done in 3.
Then expect to wait anywhere from a couple days to a few weeks for IOE. This usually takes two 3-day trips to complete.
So if you started say Oct 1, that means you'd finish ground by late October, spend November in Sims, and be done with IOE by mid-December, assuming no big delays..
