How it works

What are Global Dates?

Global Dates are international celebrations recognized by the United Nations and other global organizations. Each date focuses on an important theme — like Tolerance, Equality, Environment, or Peace.

At Class2Class.org, we turn these dates into opportunities for global collaboration. Teachers can choose a date, use one of our ready-to-use project ideas, and invite their students to connect with classes in other countries.

“I really enjoyed this meeting; very well organized and helpful. I also really like the video about COIL because it would be helpful to share with colleagues and admin to get more teachers to see the educational benefits and philosophy behind the method. Also, I really like the puzzle method to co-create a document Thanks so much for all you do C2C team!”
