Tzolk'in - haab'

The combination of a Haab' and a Tzolk'in date identifies a day in a combination which does not occur again for 18,980 days (52 Haab' cycles of 365 days times 73 Tzolk'in cycles of 260 days, approximately 52 years), a period known as the Calendar Round . To identify days over periods longer than this, Mesoamericans used the Long Count calendar.

Instead, HE uses the "beginning of human era" as its epoch , arbitrarily defined as 10,000 BC denoted year 1 HE, so that AD 1 matches 10,001 HE. [1] This is a rough approximation of the start of the current geologic epoch , the Holocene (the name means entirely recent ). The motivation for this is that human civilization (. the first settlements , agriculture , etc.) is believed to have arisen within this time. Emiliani would later propose that the start of the Holocene be fixed at the same date as the beginning of his proposed era. [2]
