Trecena (13-day period) Tochtli
The thirteen day period (trecena) that starts with day 1-Tochtli (Rabbit) is ruled by Xiuhtecuhtli, Lord of the Year. Tochtli is the last trecena of the sacred year. It signifies the end of one cycle and the beginning of a new one. These are 13 days associated with the mystical sacrifice proper to the vanguard of another age: it is an auspicious time, one great workers united in their goals; it is also a dangerous time, one of great risks requiring great courage and diligence. These days remind us of the old god, the first god, who both separates and unites the worlds of dreaming and waking: somewhere between winter and spring, something wakes in the dreaming heart which endures across the span of the cycling ages. These are good days to focus on the needs of others; bad days to focus on one's own needs.
