The honest overview
There are many good Mayan calendar calculators — and each kind is strong at something different. One tells you your Kin and solar seal in seconds, another walks you through the Dreamspell cycles day by day, the next maps the full Long Count with the Haab calendar. This page lines up the common kinds fairly, so you can find the one that fits you — no gloss, and without talking any of them down.
We're one of the providers ourselves, with Birth Codex. So below you'll find, transparently, what each kind of calculator stands for and where our own strength lies: we show your Tzolk'in signature — Kin, solar seal, galactic tone and oracle — not in isolation, but woven into 23 cosmic systems in all, in English and without signing up.
The rows describe typical traits of each kind of calculator (as of August 2026) — individual tools may differ. “Yes” or “No” refers to the freely usable calculator; some tools also offer deeper, paid options on top.

| Calendar appsYour daily Kin on your phone | Primarily English | Basics free | Account/subscription common | Daily Kin, Dreamspell cycles | Sometimes moon phases | Short, day by day |
| Classic Maya softwareLong Count, Haab & Tzolk'in in full | English/Spanish | Partly paid | Usually yes (desktop) | Long Count + Haab + Tzolk'in | No — pure Maya domain | Data tables, little prose |

“Tzolk'in” is the sacred 260-day calendar of 13 galactic tones and 20 solar seals. Birth Codex computes it using the Dreamspell correlation by José Argüelles. The full Long Count and the Haab solar calendar are the domain of classic Maya software — not ours.
The most common kind: lean calculators that name your Kin, your solar seal and your galactic tone from your birth date in seconds — often localized, free, and usually without an account. Their strength is simplicity: enter the date once, and you're done. What they deliberately don't offer is depth — the meaning of your signature stays short and the same for everyone, and further systems aren't the goal.
Then there are apps that bring the Dreamspell rhythm into your day: the Kin of the day, the 13-Moon count, small prompts to pause. Their strength is that daily companionship on your phone. In return, the interface is often English, the full scope usually runs through a subscription, and saving usually needs an account. If you love the Kin of the day, this is a good home.
For anyone who wants to know exactly, there are specialized programs that map the entire Maya calendar: the Long Count, the Haab solar calendar and the Tzolk'in, plus date conversions across millennia. This is the most thorough kind — and also the most demanding: usually English or Spanish, often a desktop program, with data tables rather than warm interpretation. Whoever wants to study the full Maya calendar gets furthest here.
Large astrology suites carry the Tzolk'in as one view among many: alongside the birth chart, transits and connection charts. Their strengths are variety and technical depth. Entry is often possible with a free account, the full scope runs through a subscription, and saving your own charts usually needs an account. The interface is mostly English — less suited to a quick first contact in your language, but ahead on breadth and detail.
Our own strength isn't delivering the most complete Maya long-count calendar — that's the domain of classic software. Birth Codex goes broad: your Tzolk'in signature (Kin, solar seal, galactic tone and your oracle of four connected powers) appears here together with 23further cosmic systems (astrology, numerology, Human Design, Chinese zodiac and more). Instead of a plain date table, your signature is written out individually for your birthday — in English (and ten more languages), computed with the Dreamspell correlation, free to try and without signing up. If you want to study the Long Count and the Haab in full, you're better served by classic Maya software — if you're after the big picture, we're built for it.

It depends on what you're looking for. If you just want your Kin and solar seal fast, a free Kin calculator in your language is the first choice. For the Kin as a daily companion, a Dreamspell app fits. Whoever wants to study the full Long Count and Haab calendar reaches for classic Maya software. Birth Codex fits if you want your Tzolk'in signature not in isolation, but woven into further cosmic systems and with an individually written interpretation — in English and without an account.
Yes, several. Besides Birth Codex there are various Kin calculators with free access. Classic Maya software and the large pro platforms, by contrast, are mostly English- or Spanish-language.
The Tzolk'in is the sacred 260-day calendar of 13 galactic tones and 20 solar seals — from it come the Kin, signature and oracle. The Long Count, by contrast, is a continuous day count across millennia that the Maya used to record historical dates. Birth Codex computes the Tzolk'in using the Dreamspell correlation; the Long Count and the Haab solar calendar are the domain of specialized Maya software.
From your birth date, the 260-day count of the Tzolk'in yields exactly one Kin (1 to 260), one solar seal (one of 20) and one galactic tone (1 to 13). Birth Codex uses the Dreamspell correlation by José Argüelles for this and also assembles your oracle of four connected powers. You only need your birth date — the time of day isn't needed for the Tzolk'in.
Some calculators — including Birth Codex and lean Kin calculators — compute your signature without an account. Calendar apps often need a subscription for the full scope, and extensive pro platforms usually require an account to save personal charts.
