"H.E." redirects here. For other uses of H.E., see He (disambiguation). "Holocene era" redirects here. For the geological epoch, see Holocene Epoch. The Holocene calendar, popular term for the Holocene Era or Human Era, is a year numbering system similar to astronomical year numbering but adds 10,000, placing its first year at the start of the Human Era (HE, the beginning of human civilization) the approximation of the Holocene Epoch (HE, post Ice Age) for easier geological, archaeological, dendrochronological and historical dating. The current Gregorian year can be transformed by simply placing a 1 before it (e.g., AD 2009 becomes 12009 HE). The Human Era was first proposed by Cesare Emiliani in 1993 (11993 HE).[1][2][3]
[edit] MotivationCesare Emiliani's proposal for a calendar reform sought to solve a number of problems with the current Anno Domini and Common Eras, which number the years of the commonly accepted world calendar. The issues include:
Instead, HE places its epoch or year one of the current era to 10,000 BC. 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 (e.g., the first settlements, agriculture, etc.) is believed to have arisen entirely within this time. All key dates in human history can then be listed using a simple increasing date scale with smaller dates always occurring before larger dates. [edit] ConversionConversion to the Holocene Era from Julian or Gregorian AD years can be achieved by adding 10,000. BC years are converted by subtracting the BC year from 10,001. A useful validity check is that the last digit of BC and HE equivalents must add up to 1 or 11.
