--- Comment #4 from Mike Kaganski <[email protected]> --- (In reply to Mike Kaganski from comment #3) > "Birashk leap year algorithm" [2], said > to be an *alternative* computation method suggested in early XX century, and > to be much less precise than both Jalali and Hijri. Indeed, not "early" but "late"; let me quote some Wikipedia: > Some predictive algorithms had been suggested, but were inaccurate due to > confusion between the average tropical year (365.2422 days) and the mean > interval between spring equinoxes (365.2424 days). These algorithms are not > generally used (see Accuracy). > ... > Iranian mathematician Ahmad Birashk (1907–2002) proposed an alternative means > of determining leap years. Birashk's book came out in 1993, and his algorithm > was based on the same apparently erroneous presumptions as used by Zabih > Behruz in his book from 1952. > ... > The accuracy of the system proposed by Birashk and other recent authors, such > as Zabih Behruz, has been thoroughly refuted and shown to be less precise than > the traditional 33-year cycle. -- You are receiving this mail because: You are the assignee for the bug.
