National Hamburger Day celebrates the ground-beef patty that Charles Nagreen and the Menches brothers both claimed to have invented at Wisconsin and New York state fairs in the 1880s — whoever got there first, the burger became the defining food of American fast-food culture. Amnesty International Day marks May 28, 1961, when British lawyer Peter Benenson published “The Forgotten Prisoners” in The Observer, launching the letter-writing campaign that became Amnesty International — now the world’s largest human rights organization. International Day of Action on Women’s Health was established to advocate for women’s reproductive and sexual health rights and to highlight disparities in global maternal health outcomes. National Flag Day Philippines marks May 28, 1898, when the Philippine flag was first unfurled at Kawit, Cavite — the blue-and-red banner whose colors reverse in wartime to signal a state of war. A patty, a letter in a newspaper, a maternal mortality statistic, and a reversible flag.
