Australia Day marks January 26, 1788, when the First Fleet arrived at Sydney Cove — celebrated as Australia’s national day with citizenship ceremonies and fireworks, while simultaneously observed as Invasion Day, Survival Day, or Aboriginal Day by many Indigenous Australians. Indian Republic Day marks January 26, 1950, when the Constitution of India entered into force — the day India became a sovereign democratic republic, marked with a grand parade in New Delhi. International Environmental Education Day promotes environmental education as a foundational school subject, connecting learners to ecological systems and climate science. Dental Drill Appreciation Day was established to recognize the dental drill — the high-speed rotary instrument invented by James B. Morrison in 1871 that transformed dentistry from extraction toward restoration and repair.
