The Andean-Amazonic New Year, also known as Año Nuevo Andino Amazónico, is observed in Bolivia on June 21 every year. This national holiday celebrates the winter solstice in the Southern Hemisphere and is rooted in the traditions of the Aymara people, an indigenous group in the Andes and Altiplano regions of South America. Approximately 2 million Aymaras reside in Bolivia, Chile, and Peru. The celebration marks the return of the sun, referred to as Willkakuti in Aymara, and was declared a national holiday under the presidency of Evo Morales, the first indigenous leader of Bolivia. The Aymara people follow their own calendar, which signifies that their nation was 5,000 years old when the Spanish conquistadors arrived in 1492. This holiday has faced opposition from right-wing Christian political factions in Bolivia.
