As the world outside becomes a smaller and an increasingly interconnected Global village, the campus of Kristu Jayanti College has also become a melting pot of diverse cultures. With students from the various states of India, the college also amalgamates a number of foreign cultures as well. The student population is a unique mixture of youth from different countries of Asia and Africa like Ghana, Costa Rica, the Middle -East, Korea etc.
As a result, the Ethnic Day is much anticipated and vibrant celebration of the cultures that the student body represents. Every year, the day is celebrated along with Onam- the harvest festival of Kerala. The students and faculty of the college come dressed in their ethnic wear and celebrate the spirit of unity and inclusiveness. The celebration of Onam in its typical style adds more colour and energy to the day.
