The twenty day-signs
The twenty signs that name the days of the tonalpohualli, the 260-day count of the Aztec or Mexica calendar. Each one pairs with thirteen numbers, and every fifth one shares a direction.
How this is made
Each entry says what the sign names, which energy rules it, the trecena it opens and its direction. What rests on the sixteenth-century sources stays in Spanish, and each page says so and links to it.
