Tzolkin: Maya Calendar

xplore the Maya calendar through its daily dates, repeating cycles and twenty day signs. Tzolkin brings the Tzolk'in, Haab and Long Count together with an illustrated count, an offline reading guide and a personal journal.

TODAY'S CALENDAR
See the current local day's Tzolk'in number and name, Haab date and Long Count. Read the number in Maya dots and bars, explore the day's historical image and spend a moment with a clearly labelled modern reflection.

EXPLORE DATES AND RETURNS
Browse a month or enter a Gregorian date. Convert a Long Count back to a calendar date. Step forward and backward, find the next return of a Tzolk'in pairing, or follow the full 18,980-day Calendar Round.

The converter uses the GMT correlation 584283 and proleptic Gregorian dates from 11 August 3114 BCE through 31 December 9999 CE. A short guide explains the date convention and how to enter BCE years.

TWENTY DAY SIGNS
Explore Imix, Ik', Ak'bal and the rest of the twenty-name sequence. Search names, older spellings or English images. Each sign includes a newly written historical note, a source reference, a modern reflection and a question for your own observations.

READ OFFLINE
Nine included articles explain the 260-day count, the Haab, the Calendar Round, Long Count notation and Maya numerals. Learn how names vary between books and languages, and read about the calendar's living context. Source titles are included as plain text.

KEEP YOUR OWN RECORD
Save dates and write personal notes. Revisit a calendar date from your journal, edit an entry or delete it when you choose. Shared calendar images include the reading, date, credit and app link while leaving your journal text out.
