If you are talking about the weekly schedule, then the Saturdays and Sundays are off for students until and unless there is a event/guest talk or some extra class scheduled. For the 1st year, the first batch had the 2nd half of Thursday free but it is quite often taken up by Guest Talks by people from reputed universities or people from industries. On a few occasions, there will be quiz during this 2nd half.
While apart from all these, there will be break after each semester. Winter break will last for 3–4 weeks while the summer break will last for almost 2 months. There will be 9 Day break for Holi and Diwali too.
Apart from these, there will be pre-listed holidays which will be given to us at the start of each semester which includes Independence Day, Republic Day, Janmashtami etc.
In case of any query, feel free to ask.
