%N Number of days in months of Ethiopic calendar.

%C The twelve months of Maskaram, Tepemt, Khedar, Takhsas, Ter, Yakatit, Magabit, Miyazya, Genbot, Sane, Harnle and Nahase each have thirty days and the remaining days are in Paguemen.

%C The intercalary month has 5 days on non-leap years, 6 days on leap years. Every fourth year is a leap year, with no exceptions. Thus, a(n) = a(n-52). - _Jon E. Schoenfield_, Feb 16 2015

%E As _Antti Karttunen_ points out, this cannot be right as there are 15 or 16 30's between pairs of 5's, not 11. - _N. J. A. Sloane_, Aug 25 2002

%E Marked one link as broken. Added two links and cf. to the Coptic Calendar. - _R. J. Mathar_, Oct 13 2008
