Year zero
Historians have never included a year zero. This means that between, for example, and , there are 999 years: 500 years BC, and 499 years AD preceding 500. In common usage "anno Domini" 1 is preceded by the year 1 BC, without an intervening year zero. Neither the choice of calendar system (whether Julian or Gregorian) nor the era ("Anno Domini" or Common Era) determines whether a year zero will be used. If writers do not use the convention of their group (historians or astronomers), they must explicitly state whether they include a year 0 in their count of years, otherwise their historical dates will be misunderstood.
Year Zero: The Silent Death of Cambodia
The documentary as a television "event" can send ripples far and wide ... "Year Zero" not only revealed the horror of the Pol Pot years, it showed how Richard Nixon's and Henry Kissinger's 'secret' bombing of that country had provided a critical catalyst for the rise of the Khmer Rouge. It also exposed how the West, led by the United States and Britain, was imposing an embargo, like a medieval siege, on the most stricken country on earth. This was a reaction to the fact that Cambodia's liberator was Vietnam – a country that had come from the wrong side of the Cold War and that had recently defeated the US. Cambodia's suffering was a wilful revenge. Britain and the US even backed Pol Pot's demand that his man continue to occupy Cambodia's seat at the UN, while Margaret Thatcher stopped children's milk going to the survivors of his nightmare regime. Little of this was reported. Had "Year Zero" simply described the monster that Pol Pot was, it would have been quickly forgotten. By reporting the collusion of "our" governments, it told a wider truth about how the world was run ... Within two days of "Year Zero" going to air, 40 sacks of post arrived at ATV ... in Birmingham – 26,000 first-class letters in the first post alone. The station quickly amassed £1m, almost all of it in small amounts. "This is for Cambodia," wrote a Bristol bus driver, enclosing his week's wage. Entire pensions were sent, along with entire savings. Petitions arrived at Downing Street, one after the other, for weeks. MPs received hundreds of thousands of letters, demanding that British policy change (which it did, eventually). And none of it was asked for. For me, the public response to "Year Zero" gave the lie to clichés about "compassion fatigue", an excuse that some broadcasters and television executives use to justify the current descent into the cynicism and passivity of Big Brotherland. Above all, I learned that a documentary could reclaim shared historical and political memories, and present their hidden truths. The reward then was a compassionate and an informed public; and it still is.
