佛涅槃的年代，有沒有不同的計算？

With regard to the year of the Buddha's Parinibbāna, the Buddhists in Southeast Asia generally put it in the year 545 BC, so in 1956 and 1957 many countries ceremoniously observed the 2,500th anniversary of the Buddha's Parinibbāna. In China, however, there are different opinions about the year of the Buddha's passing away, the generally acknowledged year being 486 BC, 59 years later than the Theravādin calendar of Southeast Asia.
關于佛涅槃的年代，東南亞佛教徒一般認為是公元前545年，所以1956年和1957年各國都舉行佛涅槃二千五百年盛大紀念。我國關于佛涅槃年代有很多不同的說法，一般公認的年代是公元前486年，與南傳佛歷相差59年。
