◉ Mayan Day Sign Calculator — Tzolk'in & Galactic Signature
Umbriel calculates your Mayan day sign free, in both the traditional count and the modern Dreamspell version — and explains why the two often disagree. The Tzolk'in is a 260-day sacred calendar pairing twenty day signs with thirteen numbers.

What the Tzolk'in actually is
The Tzolk'in cycles twenty named days — Imix, Ik', Ak'bal, K'an and so on — against the numbers one to thirteen. Because 20 and 13 share no factors, a given pairing like 4 Ajaw returns only once every 260 days. This calendar has been kept continuously for well over two thousand years and is still in daily use by Maya calendar keepers in Guatemala.
There's a genuine fork here. The traditional count follows the correlation that has run unbroken to the present day. The Dreamspell — a 1980s system by José Argüelles that produces a 'galactic signature' with a colour, seal and tone — uses a different correlation and skips leap days, so it often gives a different answer.
Umbriel shows you both, clearly labelled, rather than picking a side. If your day sign here doesn't match one you were given elsewhere, this is almost always why.

Common questions
Why is my Mayan day sign different on other sites?
Because two different systems are in circulation. The traditional Tzolk'in count and the 1980s Dreamspell use different correlations, so they frequently disagree. Umbriel shows both rather than presenting one as the answer.
Do I need my birth time?
No — the Tzolk'in day sign depends only on the date. Days change at dawn rather than midnight in traditional practice, so a birth in the small hours may sit on the previous day sign.
Is the Tzolk'in still used?
Yes. Maya calendar keepers, particularly in the Guatemalan highlands, have maintained the count continuously. It is a living calendar, not a historical curiosity.
Is this calculator free?
Yes, both systems, no account needed.
