Background about the International Day of Women and Girls in Science

The International Day of Women and Girls in Science is observed every year on 11 February to recognize the important role of women and girls in science, technology, engineering, and mathematics (STEM). The day was established by the United Nations General Assembly (UNGA) in 2015 and has been observed annually since 2016.

It aims to promote gender equality, encourage more girls to pursue careers in science, and ensure equal opportunities in scientific research and innovation. The observance highlights the contributions of women scientists and supports inclusive and sustainable development.
