Hey, hope you are doing well!

No, there is no holiday for the occassion of Onam in Manipal Institute of Technology.

But the students and staff come together and make all the necessary arrangements to celebrate the festival in the campus itself on the sunday of that week .

Its celebrated quite in a grand way by contributions of students and staff, one of the canteens is pre-booked for the fooding, functions are arranged etc. It is a proper celebration that takes place in the institute campus itself but there is no official holiday for Onam.
(Confirmed from the student organizer of the festival)
