Each day of the 260-day Tzolk'in joins one of the twenty day signs with a number from one to thirteen, and this is the first of those thirteen numbers, or tones. The pairing of thirteen numbers with twenty signs produces 260 unique combinations before any repeats, which is what gives the sacred count its length. In living Maya daykeeping the coefficient is simply the number itself, jun, one, and a day of number one is generally felt as a beginning, the first and gentlest step of the thirteen-day trecena that its day sign opens. The name recorded here, Magnetic, together with its keyword of unity and intent, comes not from traditional Maya practice but from the modern Dreamspell system devised by Jose Arguelles in the 1980s; it is a New Age overlay distinct from the Maya count and should not be mistaken for it. The number one and its role in the 260-day cycle are the authentic element.
Because the Tzolk'in is a 260-day count generated by running thirteen numbers against twenty named day signs, 13 times 20, every day in the count carries both a number, one through thirteen, and a sign name, and the same numbered sign recurs only once every 260 days. The names commonly attached to the thirteen numbers in popular literature today, Magnetic, Lunar, Electric, Self-Existing, Overtone, Rhythmic, Resonant, Galactic, Solar, Planetary, Spectral, Crystal and Cosmic, are not traditional Maya terms; they originate with Jose Arguelles's Dreamspell system of 1987, which borrows the Tzolk'in's 13 by 20 structure but runs its own separate, non-equivalent count under these invented tone names.
