The Equinox Festival, taking place in Macapá, Brazil, celebrates the astronomical phenomenon where the Sun is directly over the Equator. Scheduled from September 20 to 22, this festival will feature national music performances, a culinary festival showcasing regional cuisine, and various cultural interventions. The entrance to the event is free, making it accessible to a broad audience.

This year's festival marks the transition from summer to autumn in the Southern Hemisphere, a change that is significant as it brings milder temperatures. The equinox itself is an astronomical occurrence that aligns with the Earth's position in its orbit and its axial tilt, which is approximately 23 degrees. In Amapá, visitors can experience this alignment visually at the tourist site known as Marco Zero, even during the Amazonian winter characterized by intense rainfall.

Traditionally, previous editions of the festival have been held at Marco Zero; however, this year's events are taking place at the sambódromo in the South Zone of Macapá. The festival not only emphasizes local culture through music and food but also highlights the importance of the equinox as a seasonal marker, drawing attention to both natural phenomena and community engagement.
