International Day of the Tropics

Observed each 29 June, the International Day of the Tropics spotlights a vast region stretching between the Tropics of Cancer and Capricorn, where warmth and rainfall shape daily life. This zone covers about 40% of Earth"s surface area, yet supports around 80% of global biodiversity, making it central to planetary health and culture.
