World Thinking Day is a celebration of ten million girls worldwide that has taken place on every 22 February since 1926. It remains a day for all Guides and Girl Scouts to think of each other and celebrate their sisters all around the world.

World Thinking Day remains one of the most important dates in the guiding calendar, and every year the theme of the event encourages members to think about the big issues affecting them and their global community. Previous World Thinking Days have tackled the subjects of poverty, gender inequality, environmental sustainability and access to education.
