- The Temple of Kukulkan at Chichen Itza will show its last brief balustrade glimmers around 29 October 2026.
- An INAH bulletin published on 28 April 2026 describes the light pattern as a year-round solar cycle rather than an equinox-only event.
- The pyramid at Chichen Itza is 30 metres high, has nine levels and forms part of the UNESCO-listed pre-Hispanic city.
The Temple of Kukulkan at Chichen Itza, Mexico, will reach the final brief glimmers of its annual solar light pattern around 29 October 2026. The date comes from a bulletin by Mexico's National Institute of Anthropology and History, which presents new research on the phenomenon beyond the equinoxes.
Temple of Kukulkan reaches its last light on 29 October
The effect is known as the Descent of Kukulcan. As the afternoon sun moves towards the western horizon, triangular patches of light appear across the pyramid's north-western balustrade and form the shape of a serpent.
According to INAH's light calendar, the triangles diminish after the autumn equinox. Five triangles are reached on 9 October, after which the shapes disappear before sunset. The final short-lived flashes on the balustrade are expected around 29 October, after which the ramp remains in shadow until the next cycle begins on 12 February 2027.
Temple of Kukulkan connects sunlight with Maya timekeeping
The latest interpretation is based on observations by four archaeoastronomers whose work appeared in the March-April 2026 issue of Arqueologia Mexicana. Their findings describe a predictable pattern of sunlight across the structure throughout the year, rather than a display confined to the spring and autumn equinoxes.
The pyramid is 30 metres high, has nine levels and measures 55.5 metres on each side, according to the INAH bulletin. Four stairways end in balustrades, including the north-western ramp where the light triangles appear. That physical arrangement links the 29 October observation date to a specific architectural feature rather than to a general seasonal effect.
The monument is part of the northern group of the pre-Hispanic city. UNESCO's Chichen Itza profile identifies the Temple of Kukulkan alongside the Great Ball Court and the Temple of the Warriors, and describes the wider site as a major centre of Maya and Toltec civilisation on the Yucatan Peninsula.
