World Peace and Understanding Day, also known as World Understanding and Peace Day, is observed worldwide every February 23. This day commemorates the founding anniversary of Rotary International, one of the oldest and largest service organizations, established by Paul Harris in 1905. It promotes goodwill and understanding among people to foster world peace. Activities typically include meetings with international speakers, discussions on global issues, and various entertainment events organized by local Rotary Clubs. Participants are encouraged to engage in community service, volunteer for non-profit organizations, and learn about peaceful conflict resolution. The day is part of Rotary’s World Understanding Month, which emphasizes charitable work and personal growth through service.
