One of the largest and most colorful festivals in Latin America, Inti Raymi is the Inca Festival of the Sun, celebrated each year in Cusco during the Winter solstice.

The Festival is held on June 24th, rather than on the 21st. As related on the PeruPage, "according to the Pacha Unachaq, a sundial used by the Incas, the sun stays some days in the same place before rising on the 24th of June." For detailed information see Inti Raymi '98 on the PeruPage web site.
