The rookie 9 graduated in January, as another user pointed out due to Shino's age/date of birth. In a Hinata flashback it was shown to be snowing when they entered the academy, implying it was also January or December then, which would mean 1 school year is actually 1 year. And the chunin exams seem to happen in July. Itachi became anbu when Sasuke started the academy.

But. It was said Itachi became a chunin at age 10 half a year before becoming anbu at 11. But if he became a chunin at 10 then at the july chunin exams he would have just turned 10 the previous month, meaning half a year later he would have only been 10 when he became anbu. Or he had just turned 11 when he became chunin.

Unless the chunin exams are not always in July. And this particular case it happened earlier?
