Wiñoy Tripantu is the Mapuche celebration that marks the return of the sun, often referred to as the Mapuche New Year. It occurs on the June solstice, which is the shortest day of the year in the Mapuche homeland in the Southern Hemisphere. Sometimes, the term We Tripantu is used interchangeably with Wiñoy Tripantu, but some Mapuche language speakers use We Tripantu for the Gregorian calendar New Year and reserve Wiñoy Tripantu for the June solstice celebration.
