(Year × 159 + 362) / 656 < 159 — the formula makes no sense. I guess you meant (Year × 159 + 362) mod 656 < 159.

Good pickup. Changed to mod. (Also corrected 362 to 363.) --Bdm 10:20, 31 January 2009 (UTC)

more complex than the Gregorian formula for leap years, but unlike the Gregorian formula has no exceptions — The "Gregorian formula" is Y mod 4 – sgn (Y mod 100) + sgn (Y mod 400) = 0 and it has no ecceptions either. — Hellerick 08:16, 18 January 2009 (UTC)

That is technically correct, but the Gregorian leap year rule is not generally stated in that way. More usually, it's stated as every fourth year, except for century years not divisible by 400, or in a similar manner that explicitly mentions exceptions to a general rule. Maybe then the Gregorian formula is more complex rather than simpler, as stated in the article? --Bdm 10:20, 31 January 2009 (UTC)
