South Korea celebrates its National Liberation Day (Gwangbokjeol) on August 15, 1945, marking the end of Japanese colonial rule - the same date as India's independence in 1947. While the dates coincidentally match, the contexts differ: India gained independence from British rule, while South Korea was liberated from Japanese occupation after WWII. The other options are incorrect: South America is a continent, not a country; South Africa's Freedom Day is April 27; and North America is also a continent.
