May Day is the international workers’ holiday rooted in the 1886 Haymarket affair in Chicago, where a labor rally for the eight-hour workday turned deadly — the date was adopted by the Second International in 1889 to honor those workers and is now a public holiday in more than 80 countries. Buddha Purnima, also called Vesak, is the most sacred Buddhist holiday, commemorating the birth, enlightenment, and death of Siddhartha Gautama — observed on the full moon of the fourth lunar month, which falls on May 1 in 2026. Save The Rhino Day was established to raise awareness for all five rhino species, whose combined global population has fallen below 27,000 due to poaching for the illegal horn trade. National Loyalty Day was designated by Congress in 1958 to reaffirm loyalty to the United States and its constitutional government. Labor, lotus, a horn, and a flag.
