### 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.
