“Xmucane – Her themes are time, cycles, creativity and divination. Her symbols are calendars, blue-green items and light. This Mayan Goddess of time created time’s calculation and the calendar along with Her partner Xpiyacoc. She continues watching over all calendar functions and acts as a prophetess because she can see both past and future consecutively. Her folkloric titles include Day’s Grandmother and Maker of the Blue-Green Bowl (likely the sky).
Mayans believe the universe began on this date in 3114 B.C.E. They also teach that time will end on December 23, 2012. Exactly what this means in terms of human evolution is left to the imagination. In either case, today is a time for fresh beginnings. Call upon Xmucane to bless your appointment book and help you make the most productive possible use of your time. Try this mini-ritual:
Light a blue-green candle secured in a bowl and place it behind our calendar. Hold your hands palms-down over the datebook and say,
‘Lady of time, see where I stand in your stream.
Grant me the perspective with which to move forward confidently,
using each day on this earth to grow and learn the ways of the Goddess.
Inspire my efforts to transform every moment of my life with positive magic.
Today, and tomorrow, and tomorrow, let my moments be filled with you.
So be it.’
Blow out the candle and keep it for other rites.”

“Xmucane and Xpiacoc (alternatively Xumucane and Ixpiyacoc) are the names of the divine grandparents of Maya mythology and the daykeepers of the Popol Vuh. They are considered to be the oldest of all the gods of the Maya pantheon, and are identified by a number of names throughout the Maya sacred text, reflecting their multiple roles throughout the Mayan creation myth. They are usually mentioned together, although Xmucane seems to be alone during most of the interactions with the Maya Hero Twins, when She is referred to as simply ‘grandmother’.
The pair were invoked during the creation of the world in which the Maya gods were attempting to create humanity. Xmucane and Xpiacoc ground the corn that was used in part of the failed attempt, although the beings created were described as being simply mannequins and not real people. These two are also invoked, often by other powerful deities, for their powers in divination and matchmaking.
Xmucane Herself also plays an integral role in the development of the Maya Hero Twins. She was at first wary of them and their mother, Xquic, and ordered them out of Her house when they were yet infants, but She would come to accept them almost as Her own sons, raising and caring for them.
Xmucane is considered by some to be the Goddess associated with the waxing moon, contrasting to the hypothetical role of Her daughter-in-law as the waning moon.”
