The academic calendar in Spanish universities tends to be similar throughout the country: lectures begin in October and the academic year ends in June. Examinations are held at the end of the first semester, in February, and at the end of the second semester, in June. However, there are some variations between universities. Lectures last for 50-60 minutes . Im really not sure about the hours because it depends entirely on what courses you plan to take and what university you want to go to. One typical schedule would run from 0900 until 1700 with a two hour break for lunch; another typical schedule would go from 0900 with no break and finish classes for the day at 1400. ( but most days you only have to come in for a few seminars. Or classes that you have on the day.
