This is the fifth 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 five, job', and five carries the sense of the centre, the point that gathers the four directions around it. The name recorded here, Overtone, and its keyword of empowerment and radiance belong to the modern Dreamspell system of Jose Arguelles, a New Age reinterpretation from the 1980s that is distinct from the Maya count and not part of traditional daykeeping. The daykeepers reckon by the number itself. The authentic element is the coefficient five and its role in the interlocking of thirteen numbers with twenty day signs that produces the 260 unique days of the sacred count still kept in highland Guatemala.
The fifth of the thirteen numbers that combine with the twenty day signs to generate the Tzolk'in's 260-day count, marking the fifth day of its trecena, past the cycle's earlier days and approaching its midpoint. Thirteen numbers is itself a significant structural choice in the Tzolk'in: the count is widely read by scholars as reflecting the number of layers in the Maya conception of the heavens, thirteen levels above the earth paired with nine levels of the underworld in some cosmological schemes recorded in colonial and epigraphic sources, though the precise correspondence between the calendar's arithmetic and this cosmological structure remains a matter of scholarly interpretation rather than an explicit statement in any single surviving text.
