Your Maya calendar date

The Tzolkʼin sacred count gives you a nawal — the day-sign and tone you were born under. Beside it sits the Haabʼ solar year and the Long Count, the way the Maya carved a full date. Not a fate; the energy you carry.

How this Maya day-sign reading is calculated

Your Tzolk'in day-sign and tone (the 260-day sacred count), your Haab' solar-year date, and your Long Count — all from your birth date alone.

We convert your birth date to a Julian day number and subtract the GMT correlation constant (584283, the Goodman–Martínez–Thompson correlation, checked against published Long Count anchors), then derive the Tzolk'in tone and sign, Haab' position, and Long Count from that single day-count by modular arithmetic.

We don't assign a Year Bearer — traditions disagree on which day-sign carries that role, so we show the count itself rather than pick one convention and call it the answer. This is the classical count, not the modern 'Dreamspell' calendar.

How this Maya day-sign reading is calculated

What is the GMT correlation constant (584283)?

It's the Goodman–Martínez–Thompson number that lines up the ancient Maya Long Count with the modern Gregorian calendar — the whole reading is built from your birth date's position on that shared count.

Why doesn't Bokki tell me my Year Bearer?

Different living Maya traditions disagree on which day-sign carries that role, so rather than pick one convention and present it as the answer, we show the count itself and leave that judgment to the tradition's own daykeepers.
