Mayan Tzolkin Date Calculator
Enter a Gregorian date to calculate its sacred Tzolk’in position (Tone + Day Sign + Kin). This tool uses the GMT correlation (JDN 584283 = 4 Ajaw).
What this calculator does
The Tzolk’in is the 260-day sacred cycle used by Maya civilizations. Every day is defined by a combination of a number (1–13) and a day sign (20 names). Because 13 and 20 interlock, the exact pair repeats every 260 days.
This calculator converts a modern calendar date into its corresponding Tzolk’in designation, including the Kin number (1–260). It is useful for personal study, cultural education, and historical calendar exploration.

Understanding your result
Tone (1–13)
The tone represents rhythm, movement, and energetic pattern. Tone 1 begins intention; Tone 13 completes and transcends the cycle.
Day Sign (20 glyph names)
The day sign gives symbolic character to the day. Examples include Imix (origination), Ik’ (breath/wind), and Ajaw (illumination/lordship).
Kin (1–260)
Kin is the absolute position in the full 260-day cycle. If your date is Kin 160, that same combination returns every 260 days.
