(Translator’s Note: In the Western year 2015 CE – the traditional Chinese Buddhist Calendar stood at 3042/43 years since the birth of the Buddha – this means that according to Chinese Buddhist tradition, the Buddha was born around the year 1029/28 BCE. If it is agreed that he lived around 80 years – then the Buddha entered nirvana in the year 949/48 BCE.)
The exact date of the Buddha’s birth occurred in the 24th year of the rule of the Zhou Dynasty monarch – King Zhao (昭王) – who reigned 1052-1002 BCE. Therefore the Buddha’s birth occurred in the year 1028/29 BCE according to Matanga. The shramana (沙門 – Sha Men) – or Buddhist monk known as Tan Mo Zui (曇謨最) – is recorded in the Wei Dynasty (386-557 CE) Book of History (魏書 – Wei Shu) as stating that the Buddha was born on the 8th day of the 4th lunar month, which was during the 24th year of the reign of the Zhou Dynasty monarch – King Zhao. The Buddha entered nirvana on the 15th day of the 2nd lunar month, which occurred in the 52nd year of the rule of the Zhou Dynasty monarch – Mu Wang (穆王) – who reigned 1001-947 BCE). This means that the Buddha died around 949/48 BCE. Throughout all of the subsequent Chinese dynasties, this tradition has been preserved and upheld. From the time of the Zhou Dynasty’s King Wang until now (1952/53) – it is agreed that 2981/82 years have passed since the time of the Buddha’s birth.’
