Currently States The traditional long chronology for Siddhartha Gautama, giving a life of roughly 563 to 483 BCE, is the dating followed by Theravada Buddhist tradition itself and repeated in older Western scholarship. Heinz Bechert's edited symposium volumes, The Dating of the Historical Buddha (Die Datierung des historischen Buddha, Vandenhoeck und Ruprecht), collect the specialists who have argued for revising it against those defending it, and record the question as still open rather than settled in favour of the now more commonly preferred short chronology.
This fact previously read 566 to 486 BCE, while the dedicated article on the dating question, and Buddhism's own origin-period fact, already read 563 to 483 BCE, the figure current reference works converge on for the long chronology, confirmed against Encyclopaedia Britannica's own Buddha entry. Corrected to match.
