The Human Era (HE), also known as the Holocene Era or Holocene calendar, is a year numbering system that adds exactly 10,000 years to the currently world-dominant Anno Domini (AD) or Common Era (CE) system, placing its first year near the beginning of the Holocene epoch and the Neolithic revolution. Human Era proponents claim that it makes for easier geological, archaeological, dendrochronological and historical dating, as well as that it bases its epoch on an event more universally relevant than the birth of Jesus Christ. The current year of AD 2012 can be transformed into a Holocene year by adding the digit "1" before it, making it 12012 HE. The Human Era was first proposed by scientist Cesare Emiliani in 1993 (11993 HE).

Cesare Emiliani's proposal for a calendar reform sought to solve a number of alleged problems with the current Anno Domini era, which number the years of the commonly accepted world calendar. These issues include:

Instead, HE places its epoch 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.

Helmut Newton, born Helmut Neustädter (October 31, 1920 – January 23, 2004) was a German-Australian photographer. He was a "prolific, widely imitated fashion photographer whose provocative, erotically charged black-and-white photos were a mainstay of Vogue and other publications."

Newton was born in Berlin, the son of Klara "Claire" (Marquis) and Max Neustädter, a button factory owner. His family was Jewish. Newton attended the Heinrich-von-Treitschke-Realgymnasium and the American School in Berlin. Interested in photography from the age of 12 when he purchased his first camera, he worked for the German photographer Yva (Elsie Neulander Simon) from 1936. The increasingly oppressive restrictions placed on Jews by the Nuremberg laws meant that his father lost control of the factory in which he manufactured buttons and buckles; he was briefly interned in a concentration camp on 'Kristallnacht,' November 9, 1938, which finally compelled the family to leave Germany. Newton's parents fled to South America. He was issued with a passport just after turning 18, and left Germany on December 5, 1938. At Trieste he boarded the 'Conte Rosso' (along with about 200 others escaping the Nazis) intending to journey to China. After arriving in Singapore he found he was able to remain there, first and briefly as a photographer for the Straits Times and then as a portrait photographer.
