You mean the Hueco Mundo arc, I guess, I think your generalizing the Arrcancar Arc.
The Arrancar Arc was everthing before they invaded Hueco Mundo.
The Hueco Mundo arc was everything up the switch from Fake Karakura fights to back to Ichigo vs. Ulquiorra.
Everthing after until Aizen's defeat was Fake Karakura Town arc.
Arrancar Arc took a little over a year.
Hueco Mundo arc was just over 2 years.
Fake Karakura Town arc was also a little over a year.
Now that I think about it the Lost Substitute Shinigami didn't even last a year.
