Cultural Day Suggestions

Hello this year I serve as both the president and a representative for my year group (year 12) on the student council. We were instructed to collect suggestions from our year groups in order to arrange a cultural day for next year. Since everyone in my year group lacks ideas, I need your advice. You can offer suggestions based on earlier initiatives you've tried in your schools that seem to work well. Thanks.
This is also my first time posting here! I hope to get some good replies.
