Tzolk’in · Cholq’ij
Your Maya day sign
Long before the calendars most of the world now uses, the Maya kept the Tzolk’in — a sacred 260-day count that pairs 20 day signs with 13 numbers. Your birthday falls on one of its 260 day-names — your kin — and that sign is read for its character. The count is still kept by Maya day-keepers today.
No birth time needed — the Tzolk’in counts whole days.
What is the Tzolk’in?
The Tzolk’in (Cholq’ij in K’iche’ Maya) is the sacred count that runs alongside the solar year. It weaves two wheels together: the 20 day signs, each with its own character, and the numbers 1 to 13, called the trecena, which give the tone. Because 20 and 13 share no common factor, a full turn of both takes 260 days, and only then does a day-name recur.
Your kin — your day sign and its number — is read as the energy you were born into. The sign gives the theme; the number gives its intensity and stage.
A living count, not a lost one
The 260-day count was never broken. Maya day-keepers (ajq’ij) in the highlands of Guatemala and parts of Mexico still track it and use it for ceremony, naming and counsel. AsterNym computes your day sign using the standard GMT correlation, the anchor most widely used to line the Maya count up with the modern calendar.
