Enter your date of birth to find your Tzolk'in day sign and tone — one of twenty sacred glyphs and thirteen numbered energies from the 260-day sacred calendar still used for divination in the Maya highlands today.
An honest note: this calculator uses the GMT correlation (584283), the constant most widely accepted by Maya epigraphers for aligning the Long Count with the Gregorian calendar. It anchors to the well-documented date 4 Ajaw 8 Kumk'u — Long Count 0.0.0.0.0 — and to 21 December 2012 (13.0.0.0.0), which lands on the same tzolk'in day, confirming the cycle. A handful of alternative correlations exist among specialists and can shift results by a few days; this tool reflects the mainstream scholarly consensus.
