UWC Day is the annual global celebration of the UWC mission and values, which takes place on 21 September every year, to coincide with the UN International Day of Peace. Each year, UWC Day has a different theme which helps to provide a central focus for the day’s actions and initiatives.

The theme for UWC Day 2019 is "Climate for Change". We are living in a time in which the consequences of climate change are increasingly devastating. On 21 September we are going to host a webinar-marathon and invite people who care about the world we live in and want to preserve it for the future generations.
