*WORLD* *THINKING* *DAY* World Thinking Day, formerly Thinking Day , is celebrated annually on 22 February by all Girl Guides and Girl Scouts . It is also celebrated by Scout and Guide organizations and some boy-oriented associations around the world. It is a day when they think about their "sisters" (and "brothers") in all the countries of the world, the meaning of Guiding, and its global impact. February was chosen as it was the birthday of Scouting and Guiding founder Robert Baden-Powell and of Olave Baden-Powell , his wife and World Chief Guide. Other Scouts celebrate it as B.-P. Day or Founders' Day.
