This is the eleventh of the thirteen numbers, or tones, that combine with the twenty day signs to form the 260-day Tzolk'in. In living Maya daykeeping the coefficient is simply the number eleven, junlajuj, falling among the high numbers of the thirteen, often felt as a day of dissolving and letting go as the trecena nears its close. The name recorded here, Spectral, and its keyword of release and liberation belong to the modern Dreamspell system of Jose Arguelles, a New Age overlay from the 1980s that is distinct from the Maya calendar and not part of traditional daykeeping. The daykeepers reckon by the number itself. The authentic element is the coefficient eleven and its role in the interlocking of thirteen numbers with twenty day signs that produces the 260 unique days of the sacred count.
The eleventh of the thirteen numbers that combine with the twenty day signs to generate the Tzolk'in's 260-day count, marking the eleventh day of its trecena, in the final stretch before the thirteen-day cycle completes and the next trecena begins with the number one again attached to a new day sign five positions further along the twenty-sign sequence. Because twenty and thirteen share no common factor greater than one, every combination of a number and a day sign is unique across the full 260-day count, a property epigraphers regard as central to why the Tzolk'in functioned so effectively as a system for naming individual days without ambiguity across a person's entire lifetime.
