Off-topic, I admit, but it may interest some of you: a mathematician friend of mine has just finished decoding the ancient, world-famous Gate of the Sun in Tiwanaku after several years of research. He claims his work provides irrefutable evidence of "divine design of the universe" because encoded in the artwork of the frieze on the megalithic gate is the same pattern of cosmically relevant numbers that are found in the sacred geometries of certain religions and to which he has been able to give scientific meaning as cosmic blueprints. The work will be published soon.

The Gate of the Sun has NOTHING to do with calendars.
It's all about the mathematical nature of God.
