The Dreamspell is an esoteric calendar loosely based on the Maya calendar constructed by New Age spiritualist and author Jose Arguelles, in 1987. [1]. It is a 13 month (364 day) calendar, with an intercalary period. This included both a 365-day solar calendar called the Haab, as well as a 260-day sacred calendar called the Tzolkin, which Arguelles postulates to be based on galactic rotation. Arguelles interprets this calendar as part of what he calls a 'radiogenetic game board' that relates to both the I-Ching and to the 64-unit DNA code.
Dreamspell was created in 1987.
It depends on what you mean by 'correct'. As calendars go, it is as correct as any other as long as it serves the needs of those who use it. A calendar is a way of reckoning time, and that's all it has to 'do', whatever that means. If you are asking about the popular predictions of the end of the world, 21 December 2012, based on the Mayan calendar, then the answer is no. It's a calendar, for goodness' sake. The cycles built into the calendar all coincide on 21 December 2012. Some conclude that this is a mystical sign that the world will end. Truth is, a new cycle of cycles begins on 22 December 2012 according to the Mayan calendar, which might mean something to people who are actually observing the Mayan calendar.
