October 20

Established by the International Osteoporosis Foundation, World Osteoporosis Day is observed on October 20 each year. The day aims to educate the public about bone health and the risks of osteoporosis, a condition that weakens bones. Health organizations worldwide host screenings, seminars, and campaigns promoting calcium intake and physical activity. Innovative programs target vulnerable groups such as older adults and postmenopausal women to prevent fractures. World Osteoporosis Day unites medical professionals, policymakers, and patients in a global effort to reduce the burden of bone disease.

Established by the United Nations, World Statistics Day occurs every five years on October 20 to highlight data's role. The day promotes awareness of statistical information for evidence-based decision making and global monitoring. National statistical offices organize conferences, exhibitions, and public lectures to showcase data innovations. Themes focus on topics such as data accessibility, data quality, and the statistical contributions to global goals. World Statistics Day encourages collaboration among statisticians, policymakers, and the public to build trust in data.
