"Women's Day" most commonly refers to International Women's Day (IWD), celebrated globally on March 8th, to recognize women's social, economic, cultural, and political achievements while advocating for gender equality and women's rights. It's a day for collective action, highlighting issues like reproductive rights, violence against women, and promoting empowerment, with UN themes often setting global focus, like 2025's "For ALL women and girls: Rights. Equality. Empowerment.".
