609 "description": "The Long Count is a continuous day count from a fixed mythological creation date (0.0.0.0.0), giving an absolute, non-repeating reckoning unlike the cyclical Tzolk'in and Haab'. It appears in inscriptions from around 36 BCE (Stela 2 at Chiapa de Corzo) and was the primary monumental dating system through the Classic period, with the latest known Classic-era Long Count inscription around 909 CE (10.4.0.0.0 at Tzibanche), after which the abbreviated Short Count took over. This conversion uses the GMT (Goodman-Martinez-Thompson) correlation (584,283), the most widely accepted constant, under which 13.0.0.0.0 fell on 2012-12-21 — the well-documented completion of the 13th baktun, not an 'end of the world' as sometimes popularly claimed.",

Together they form the 52-Haab' (18,980-day) Calendar Round, which repeats rather than counting a continuous numbered year. Both predate and outlasted the Long Count, and the Tzolk'in and Calendar Round remain in active ceremonial and agricultural use today among Maya communities in the Guatemalan highlands and parts of Chiapas, Oaxaca, and Veracruz — so this era is left open-ended.",
